EdiSyn 0.31 Release

Some tiny improvements for EdiSyn:

ADD: Bookmarks (Ctrl + Shift + 0..9 for set, Ctrl + 0..9 for jump to bookmark) in the picture Bookmark 5 is set.
ADD: Bookmark bar can be switched on/off
FIX: Crash when close a Tab via key removed (Focus issue)
FIX: Better/faster creation of new Editor pages
CHG: Show only every 5th line number, looks not so crowded
FIX: TabStop setting for Replace Dialog (use tab from search to Replace edit field)
CHG: Use MUI Requesters instead of EasyRequest -> looks nicer and the Window behind gets redraw events.
