clear repository for fresh vundle installation

add zenburn color scheme
add some syntax definitions
add filetype settings
add settings

The old 'bootstrap' and 'config' folders were merged into this one
'config' folder because Vundle does not seem to need any bootstrapping
for the dirsettings plugin to work properly.
