Add regex scrollback buffer search

This adds a new regex search which allows searching the entire
scrollback and jumping between matches using the vi mode.

All visible matches should be highlighted unless their lines are
excessively long. This should help with performance since highlighting
is done during render time.

Fixes #1017.
