This release contains several GUI enhancements in Tkenv, and several bugfixes.

Tkenv:
- display string enhancement: connections with zero line width ("o=,0") now do not appear in the network graphics.
- added object icons to inspector listboxes
- added Run/Fast/Express buttons to every module inspector window, as well as a "Find/inspect messages, queues, etc within this module" button. These functions are all available via hotkeys too (F5,F6,F7,Ctrl+S).
- added "Copy to clipboard" and "Save window contents" toolbar icons to all text windows. (Copy has already been available with Ctrl+C.)
- main window position gets saved and restored

Bugfixes:
- fix: gamma_d() was bogus for the alpha<1 case [reported by Patrick McDonnell]
- fix: worked around a fiber-related Visual C++ problem that caused certain activity()-based modules crash when the simulation was restarted.
- fixed a bug which sometimes caused Tkenv to crash when inspecting an internally refcounted message.
- fixed a bug in Tkenv's setObjectListResult() [crash reported by Rodolfo Ribeiro Gomes and others]
- fix: on some Linux systems, Tkenv used unreadably small font size in some dialogs
- opp_msgc improvements: don't accept reserved words as identifiers; added OMNeT++ version check into generated code
- fix: the simulation can now be in a directory whose path name contains spaces (e.g. "Program Files"); opp_nmakemake also fixed to accept include paths with spaces.
- many other minor fixes and improvements; see the ChangeLogs of the corresponding source directories for more details.
