[ Lavi ] weak spacing before 'colon'

[Deevad]

The spacing before the colon in the font Lavi is a bit weak. The consequences: many time a empty space was added before the colon to workaround this issue. This is not correct. The problem is revelant in this discution ( https://github.com/Deevad/peppercarrot_ep14_translation/pull/3#issuecomment-175467423 )

A correct spacing should be setup in the font Lavi ( Note: semi-colon, and other punctuation symbols might be affected )
