Split Pragha between the application and a library to link the plugins.

This results in a true plugin system, where other developers can implement 3rd party plugins for extend Pragha.

I wrote a small sample to test how it works:

• https://github.com/pragha-music-player/pragha-sample-plugin

...that implements the option to start a CD burner application with the current playlist.

Dont remove old widgets when remove extra button on toolbar.. and append an api to it.

Sample plugin:

... and although it is (and will continue to be) experimental, it also adds plugin support in windows... 😉

...and now with Lirics, Artits bio and recomendations.. 😄
