hybrid.vim theme for airline uses crimson color for status line if any
modifications to the buffer are detected. It looks annoying since we
deal with it every day. Let's do not be too obsessive here and get rid
of special color at all - fortunately it's redundant as we have [+] sign
to emphasize that unsaved changes are detected.

hybrid.vim theme for airline uses pretty strange palette for both visual
and insert modes. Despite looking *strange*, one may consider it as a
design decision, however, the replace mode uses the same palette for
statusline as the normal mode and hence looks consistent. Visual
comparison could is located here:

This patch makes things consistent and use the same colors for the
status line, and different colors for mode indicator.
