[FFe] Add Persian keyboard layout and swipe cursor movement

[Michael Sheldon]

We have updated packages built for the OSK which add support for Persian input and for more convenient cursor movement (bug 1566172). These packages also include a number of bug fixes to improve OSK interaction in the desktop/laptop/tablet form-factors.

This adds one new package: ubuntu-keyboard-persian which follows the same structure as all the existing ubuntu-keyboard-<language> packages.

These packages are optional and the OSK functionality is only enabled by default in unity8.

I accepted this

thanks for the work, is adding a persian input really that important that it needs to land this cycle rather than at the start of the next one?

the bugs fixes might make more sense to get in but you give little detail on what issues are fixed or what is improved, could you give some specifics?

the purpose of a ffe bug is describe why the changes are really worth landing now despite the extra work and regression potential they might carry, that bug lacks detail to be convincing though

... or if Laney says it's ok let's say it is ;-)

^- we mid air collided on that comment, but I think that seb128's comments are valid, please make your FFe bugs have more detail next time
