Support recenter on C-l

- Since the edit buffer will typically be small, we can assume that
  the user doesn't really wish to recenter the edit buffer, but the
  target buffer.  This is how isearch behaves as well.
Yank word on C-w

- If a region is active in the search buffer, yank that.
- Otherwise expand search like isearch does.
added new option: phi-search-case-sensitive
Merge pull request #6 from pmachata/master

Support recenter on C-l
improvements

- almost all commands are available in both search/replace
- recenter is compatible with scroll commands
- "last-query" is shared among search/replace
fixed phi-search-complete
moved variables

perhaps this does not affect warnings (?)
