Title: Handle '-i' before '-g' or '-G' properly

`ag -i -g ` should perform case insensitive filename search

`ag -i -G ` should perform case sensitive search for needle in case insensitive filenames

`ag -G -i ` should perform case insensitive search for needle in case sensitive filenames

`ag -i -G -i ` should be case insensitive for both

Fix #302
