Close #1915

Close #1775

Fix the reminiscence of some extended settings and work-around the lack of persistence of Equalizer settins between songs by deactiving the UI. At least it is consistent.

Ref #1752 and complaints on IRC. #1866 and #1795

This reverts commit 4774dc6c.

Qt: don't check if a variable is a command. This will show radio buttons for zzom, crop & aspect-ratio.

Hopefully fix #1910 'When I use the command "mrl playlist_add vlc_play", "playlist_add" used to return the index of the item added to the playlist wheras in the last nightly build, "playlist_add" just add 0 to the stack. Thus, "vlc_play" just play the first element of the playlist in spite of playing the desired file.' ... and fix an unrelated compilation warning which ended up being a bit more complex to fix than I though.

(What about some GCCisms for static type checking here... later)

...and use Windows built-in function for command line parsing.

Note: this is still buggy as deletng items does not update other item's IDs
