Include Prewritten Licenses

Recently granite received About menu License support.

One has to add the actual text of the license ever so carefully in Vala to avoid weird spacing issues. For example:

construct {
   about_license = """This program is free software: you can redistribute it and/or modify it
under the terms of the GNU Lesser General Public License version 3,
as published by the Free Software Foundation.

This program is distributed in the hope that it will be useful, but
WITHOUT ANY WARRANTY; without even the implied warranties of

PARTICULAR PURPOSE. See the GNU General Public License for
more details.

You should have received a copy of the GNU General Public License
along with this program. If not, see <http://www.gnu.org/licenses>""";
}

It would save some hassle, a small amount of disk space and increase uniformity if granite already included possible licenses and they could be activated by something like:

construct {
   about_license = gplv3;
}

or

construct {
   about_license = gpl2plus;
}

Even better if granite could automatically insert program_name for personalization. For example:

"SomeAppTitle is free software: you can redistribute it and/or modify it..."
