adapted a sizer parameter in resource edit
 plan to extend Trace2UML for Qt signal and slot. First extended the help screen
extended the parser to understand a connect ("%") line
Trace2UML now supports a connection database (a Qt feature)
implemented signal and slot handling
changed the syntax a little bit, because of problems with the thread context
the parsing of timestamp and thred id is done earlier
Trace2UML supports multiple connections (in Qt mode)
bugfix: a signal can be connected to multiple slots, but a slot is aways triggered by only one signal
No functional changes, just the usual model element renames (grrr)
Release 1.3.0
