Added path expanding for dest in lineinfile
Added common file arguments to lineinfile so the module gets owner,
group, mode and SE options.
Decorated existing example to demonstate usage of file options and added
a couple more examples
Message is not set accordingly when file attributes were changed
'absent' handling code now handles the case where the file doesn't
exists (was issuing a Traceback before)
File attribute handling code has been added to the 'absent' handling
function too.
File attributes handling has been grouped in 'def check_file' since it's
required in both places.
'absent' mode now returns a message like it's counterpart 'present',
telling if file attributes were altered and if lines have matched.
