Fix recent repo view size issue

getMessageHeight() calculates height under assumption that given view's
wrap option (view.Wrap) is true, and createMenu() does not set wrap
option as true. this causes gocui set improper view's height when lines
in view needs to be wrapped.
add *gocui.View as parameter in getMessageHeight(), and calculates
view's height depend on its wrap option.

resolve issue #354
