* Added missing tooltips for existing buttons for list management (add line,
remove line, move line, clone line)
* Shortened existing tooltip texts to a minimum
* Fixed incorrect tooltip texts
* Changed order of buttons to 1. move item, 2. delete item, 3. add item, 4.
clone item
* Changed tooltips "click to toggle enable/disable rule" to "disable rule" and
"enable rule" corresponding to the current state, respectively.
Make "src" the implicit "/usr/local" so that nobody can
sneak in weird files in the base file system or potentially
overwrite them.
This is the last time, I swear... :)
