Dpymenus

Added

- `PaginatedMenu`s can now pass in an `Embed` to `on_cancel` and `on_timeout`
to override the default embeds.
- Created a little logo.

Changed

- Replaced old demos with a new demo .gif for the README showing off a `PaginatedMenu`.
- Modified build script to avoid the possibility of uploading old source code to PyPi.
- Updated all `__repr__` strings to more accurately capture the object representation.
- `start_session` is now marked private with `_`.
- Moved license in setup to display properly with `pip show dpymenus`.
- Updated `discord.py` requirement to `1.3.4`.

Added

- `PaginatedMenu`s now have an optional argument: `page_numbers`. If set to `True`, embeds will generate a footer with
the current and total page numbers. *This option will override user-defined footers.*

Changed

- The session handler now stores sessions as a tuple `(user_id, channel_id)`
instead of just `user_id`.
- The default timeout page now has the title 'Timed Out' instead of the last pages' name.
- **Breaking:** `set_user_inactive()` is now `close_session()`

Fixed

- Users can now have multiple menu sessions cross-channel and guild.
- Fixed a timeout error in a `TextMenu` where it did not break after the exception occurred.
- Fixed a timeout error in all menus where it attempted to remove null data from the session list.
- Fixed an issue where other menu buttons would call your own menu actions.
- Added a missing `await` in the README example for `PaginatedMenu`.

Added

- A new menu type, PaginatedMenu. See examples on how to use this feature. *`PaginatedMenu`s are very basic currently.*

- Users can now only create a single menu instance at a time in order to prevent abuse or confusion. *Note that if you
are overriding `on_cancel` or
`on_timeout`, you need to call `set_user_inactive()` alongside
`self.active = False` now.*

Fixed

- `ButtonMenu`s no longer send new messages inside DM channel types instead of the expected default behaviour.
