Subject: - some fixes for qt5 compatibility - hook.dll no longer creates a
 dump and uninstalls it if an exception is reported that doesn't originate
 from it - NCC used read-only transactions again because otherwise solid
 archives become unusably slow. - removed the integrated nexus browser - the
 mod description and motd are now rendered in QTextBrowser. This (and the
 above) eliminates the dependency on qtwebkit - removed the direct file
 download for mod files - reduced CPU usage during downloads by invalidating
 only one column of the download list. This widget still needs to be replaced
 - added the complete filename as an option for the modname - applications
 that require elevation can now be started by invoking an elevated secondary
 ModOrganizer instance - MO will now register nexus file servers and provides
 a settings dialog to pick preferred servers. (This preference is not used
 yet) - worked around 1-2 bugs in QSortFilterProxy - handling of nxm links is
 now done by an external application. This allows the registration of
 different applications depending on the game - integrated fomod installer now
 displays the screenshot in a scalable view - bugfix: integrated fomod
 installer didn't name output files correctly if the name differs from the
 source name - bugfix: a successful login to nexus was (sometimes?) not
 correctly detected as a success - bugfix: top-level entries in
 QtGroupingProxy were sometimes incorrectly displayed as groups - bugfix:
 GetPrivateProfile... optimization could cause null-pointer indirection -
 bugfix: GetCurrentWorkingDirectory caused buffer overflow in case of
 pre-flighting (buffer size 0) - bugfix: configurator plugin now also uses qt5
 (it's currently broken though)
