minor doc reformatting

now version_added < 1.3 does not get shown, up from 1.0
option's version_added is also now filterd against this threshold
module version_added is more prominent
exaples now uses pure rst instead of intermingled with html formatting
aliases now shown in description for options
bad version fields now throw warnings instead of exceptions
ansible-doc errors now show traceback in very very verbose mode, for easier debugging
