Layouts are now defined in yaml files at latinime/java/assets/layouts. The new system makes simple layouts significantly easier to add.

Many layouts still need to be ported over to the new system and some bugs still remain. The old layout system and XML layouts will need to be removed.

The texts for more keys have been updated:
* morekeys_a should now include only letters relevant to the active language
* morekeys_misc_a should include misc letters (accents, etc) not specifically needed for typing in the language

The above still needs to be applied to most other languages. Only QWERTY has been updated with the new morekeys system. Other layouts still need to be updated.
