Subject: [PATCH] new property argument to widget _tell functions

actually the _tell function won't handle the new argument.
Coming patches will handle them.

it will need now something like this:

echo '0 widget_tell widget property value'

where property can be anything used in the awesomerc file,
that means what will be supported. Like: fg, fg_end, width, font...

(actually it ignores the property value and changes what have been changed in
the past as well.)
