make the whole xdg/dev directories /configs etc more sense making. now theres just one config you can directly copy into your home and use without editing. the same config can be used while developing, the Makefile just overrides 2 xdg variables. also the scripts can be a bit simpler now

+// link follower for uzbl
+// requires http://github.com/DuClare/uzbl/commit/6c11777067bdb8aac09bba78d54caea04f85e059
+//
+// first, it needs to be loaded before every time it is used.
+// One way would be to use the load_commit_handler:
+// set load_commit_handler = sh 'echo "script /usr/share/uzbl/examples/scripts/linkfollow.js" > "$4"'
+//
+// when script is loaded, it can be invoked with
+// bind f* = js hints.set("%s",   hints.open)
+// bind f_ = js hints.follow("%s",hints.open)
+//
+// At the moment, it may be useful to have way of forcing uzbl to load the script
+// bind :lf = script /usr/share/uzbl/examples/scripts/linkfollow.js
+//
+// The default style for the hints are pretty ugly, so it is recommended to add the following
+// to config file
+// set stylesheet_uri = /usr/share/uzbl/examples/data/style.css
+//
+// based on follow_Numbers.js
+//
+// TODO: fix styling for the first element
+// TODO: emulate mouseover events when visiting some elements
+// TODO: rewrite the element->action handling
