authentication_handler implementaion

Authentication handler allows to delegate http authentication to external
program. It introduces one new configuration variable: authentication_handler.
Note that this commit does not affect uzbl behaviour unless this variable is
set.  Also updated README documentation, default config and added example
authentication script.
