Scour

* Add support for removal of editor data of Sketch. ([37](https://github.com/scour-project/scour/issues/37))
* Add option `--verbose` (or `-v`) to show detailed statistics after running Scour. By default only a single line containing the most important information is output now.

* Add functionality to remove unused XML namespace declarations from the `<svg>` root element. ([14](https://github.com/scour-project/scour/issues/14))
* Restore unittests which were lost during move to GitHub. ([24](https://github.com/scour-project/scour/issues/24))
* Fix a potential regex matching issue in `points` attribute of `<polygon>` and `<polyline>` elements. ([24](https://github.com/scour-project/scour/issues/24))
* Fix a crash with `points` attribute of `<polygon>` and `<polyline>` starting with a negative number. ([24](https://github.com/scour-project/scour/issues/24))
* Fix encoding issues when input file contained unicode characters. ([27](https://github.com/scour-project/scour/issues/27))
* Fix encoding issues when using `stding`/`stdout` as input/output. ([27](https://github.com/scour-project/scour/issues/27))
* Fix removal of comments. If a node contained multiple comments usually not all of them were removed. ([28](https://github.com/scour-project/scour/issues/28))

* Ensure Python 3 compatibility. ([8](https://github.com/scour-project/scour/issues/8))
* Add option `--nindent` to set the number of spaces/tabs used for indentation (defaults to 1). ([13](https://github.com/scour-project/scour/issues/13))
* Add option `--no-line-breaks` to suppress output of line breaks and indentation altogether. ([13](https://github.com/scour-project/scour/issues/13))
* Add option `--strip-xml-space` which removes the specification of `xml:space="preserve"` on the `<svg>` root element which would otherwise disallow Scour to make any whitespace changes in output. ([13](https://github.com/scour-project/scour/issues/13))

* Fix ingoring of additional args when invoked from scons.

* Add option `--keep-unreferenced-defs` to preserve elements in `<defs>` that are not referenced and would be removed otherwise. ([2](https://github.com/scour-project/scour/issues/2))
* Add option to ignore unknown cmd line opts.

* Add option `--shorten-ids-prefix` which allows to add a custom prefix to all shortened IDs. ([1](https://github.com/scour-project/scour/issues/1))
