Tksheet

Changed:
- Edit validation will now also be triggered for undo and redo [256](https://github.com/ragardner/tksheet/issues/256)
- Cell text editors and dropdowns have their own shared background and foreground colors [255](https://github.com/ragardner/tksheet/issues/255)

Fixed:
- `7.2.22` regression when using cell text editors and normal dropdown boxes

Added:
- Autocomplete for `"normal"` state dropdown boxes
- Python `3.13` support badge
- `"disabled"` state for dropdown boxes
- docstrings for enable/disable bindings and extra bindings functions to help with arguments

Fixed:
- Alternate row colors no longer blend with clear single cell selection box
- Highlights and alternate row colors not blending with `show_selected_cells_border=False`
- Tab key with `show_selected_cells_border=False` not updating selected colors when using highlights
- Treeview `selection_set()`/`selection_add()` now only use iids that are in the tree, will not generate an error if an iid is missing
- Error on close text editor

Improved:
- Code: minor type hinting
- Code: variable name clarity

Fixed:
- Storing functions in event data using `pickle` causes error [253](https://github.com/ragardner/tksheet/issues/253)

Added:
- Basic alternate row colors option

Changed:
- `float_formatter()` by default will no longer accept inputs that end in `"%"`
- `percentage_formatter()` default `format_function` renamed: `to_float()` -> `to_percentage()`
- Events no longer emitted for cut, paste or delete if the sheet has not been edited, for example due to read only cells [249](https://github.com/ragardner/tksheet/issues/249)
- `__init__()` calls now use `super()`

Added:
- Options for percentage formatter:
- `format_function` option `to_percentage()`
- `format_function` option `alt_to_percentage()`
- `to_str_function` option `alt_percentage_to_str()`

Improved:
- Documentation for data formatting

Fixed:
- Error when pasting into empty sheet
- Potential error if using percentage formatter with more than just `int`, `float` and wrong type hint [250](https://github.com/ragardner/tksheet/issues/250)
- Only show the selection box outline while the mouse is dragged if the control key is down
- `index` and `header` `Span` parameters were not working with function `readonly()`

Added:
- Shift + arrowkey bindings for expanding/contracting a selection box
- Functions for getting cell properties (options) [249](https://github.com/ragardner/tksheet/issues/249)
- Ability to edit index in treeview mode, if the binding is enabled

Improved:
- Very slight performance boost to treeview insert, inserting rows when rows are hidden

Fixed:
- Inserting rows/columns with hidden rows/columns sometimes resulted in incorrect rows/columns being displayed
- Treeview function `insert()` when using parameter `index` sometimes resulted in treeview items being displayed in the wrong locations

Changed:
- Using function `set_currently_selected()` or any function/setter which does the same internally will now trigger a select event like creating selection boxes does
- iids in Treeview mode are now case sensitive
- Treeview function `tree_build()` when parameter `safety` is `False` will no longer check for missing ids in the iid column
- Treeview function `get_children()` now gets item ids from the row index which provides them in the same order as in the treeview
- Add parameter `run_binding` to treeview functions `selection_add()`, `selection_set()`
- Slight color change for top left rectangle bars

Added:
- Initialization parameters `default_header` and `default_row_index` can now optionally be set to `None` to not display anything in empty header cells / row index cells
- Parameters `lower` and `include_text_column` to treeview function `tree_build()`
- Treeview function `bulk_insert()`
- Treeview function `get_nodes()` behaves exactly the same as `get_children()` except it retrieves item ids from the tree nodes `dict` not the row index.
- Treeview function `descendants()` which returns a generator
- Treeview property `tree_selected`
