Revert "New version of kak without bash dependency"

This reverts commit e81eaf8deca427652c0ddbcdf35d5ceae9bbe6e1.

kakoune actually *still* depends on bash as of today:
https://github.com/mawww/kakoune/issues/81#issuecomment-36822364
Add back 'bash' dependency to kakoune-git
Added package 'playframework' (ie "version 1")

I am going to switch AUR 'playframework' (ie "v1") by "v2" so this "v1"
will no longer exist in AUR. This commit is thus intended to be some kind
of backup.
