mostly underhood work:
-implement core functionality to support autosave (a KLockFile patch is awaiting)
-implement core functionality to support inline markup insertion and deletion.
currently undoing paired tag insertion with inclusion of other tags doesn't work properly -- due to be solved after I get some sleep.
-draw XLIFF inline markup as buttons -- much like Trados does ;)
-rename tagrange.* to catalogstring.*
-extract some code from jobs.* into newly created tmscanapi.* and tmentry.h
-cleanup headers and comments that ain't needed no more
