Added new option to find panel of space text which toggles
case-esensitive search.
Additional changes:
- Send NC_TEXT|NA_EDITED when removing markers in find_and_replace modifier
this prevents "sticked" markers which disappears on first redraw when
search text wasn't found
- Do not show "Text wasn't found" error when text to be searched is contained
in the end of buffer and it's selected. Replacing/marking used to happen, but
this popup message was really annoying for this case.
TODO: It's incorrect to use UI_GetThemeColor4ubv from this operator
ui/ --> startup/bl_ui
op/ --> startup/bl_operators
scripts/startup/ is now the only auto-loading script dir which gives some speedup for blender loading too.
~/.blender/2.56/scripts/startup works for auto-loading scripts too.
