Cleaning and refining the xintrc

-   Modularizing dotfiles via xbindkeys (Now I start at booting
    xbindkeys to divide some not window-manager specific keybindings
    from i3)
-   I removed feh and now I am using xsetroot to set my wallpaper
-   Added ctr_r as a composer key
-   Xautolock now generates a nice blurred image in the background, when
    the PC is locked
-   Fixing the font rendering
Now beets can speak MPD :D
