Convert over libpcbsd to Qt5.
Also add a new SingleApplication class to the UI library.
To Use:
1) LIBS += -lpcbsd-ui in the *.pro file
In main.cpp
2A) #include <pcbsd-SingleApplication.h>
2B) To use, only two major differences between old QSingleApplication
PCSingleApplication app(argc,argv);
if(!app.isPrimaryProcess()){ return 0; }
2C) connect(app, SIGNAL(InputsAvailable(QStringList)), <window>, <slot>)
Rename the src-qt4.pro as src-qt5.pro (since it is in the src-qt5 tree)
Merge branch 'master' of github.com:pcbsd/pcbsd
