Replaced Lua pattern matching with Regex via Scintilla and TRE.

As a result, changed `ui.find.lua` to `ui.find.regex`
Also removed luautf8 dependency since it is no longer needed.
Regex replacements cannot contain embedded Lua code.
Jumping to "find in files" results selects those results instead of just jumping
to their respective lines.
