changed shortcut for scratchpad to mod-tab instead of mod-e since mod-e is used for changes in physical monitors in xmonad
added support for HDMI output to be recognised automatically. Also set resolution of laptop display manually since the auto value was incorrect
added cabal bin path to path
changed tabnext/prev commands to bufnext/prev, since I should learn to use vim buffers and not misuse tabs for it
added NERDTREE plugin to vim
