qmake cleanup (#43)

* cleanup: get the include and lib path from r2

* clean up of the main project file

* check if r2 is available

* corrected r2 binary name m(

* qmake error if libr not found

Because the project won't build if r2 or the paths are not found emit
an error

* removed comments and unused variable

* Add 'make install' for AppImage

* Use 'make install' in travis build
