Implement "translationdomain" attribute for extensions

Will allow extensions to ship their own message catalog used for
translation of the extension#s strings.

Needs to be set on the root <inkscape-extension> element of the .inx

Currently supported values:
- unset: use default textdomain (which happens to be 'inkscape')
- 'inkscape': use Inkscape's message catalog
- 'none': disable translation for the extension's strings
