Add 'Profile' build configuration (similar configuration to many game engines).
This should be the main configuration for development. In the future, this will include incremental linking and asserts.
* Fixed compiler error when trying to compile SDK Launcher in debug (static lib was not compiled with static link runtime).
* Documented most stuff in basepanel.cpp
* Split some logic into dedicated functions in basepanel.cpp
* Implemented VDF parser from Matthias Moeller.
* Parse playlist file and load all playlists into the combo box.
