inhibit change hooks during (insert content)

`yas-expand-snippet' narrows to a 0 size region before doing (insert
content), this confuses cc-mode's before-change-functions that
invalidate some cached information. Binding `inhibit-modification-hooks'
to `t' prevents calling these functions.

Fixes #404.
