Remove code that checks for the edje theme file since the execution order is non-linear

Introduce the EDJE_FILE_NAME global constant to avoid having magic strings all over the place
Add a check for the edje theme file in edje_group.__init__()
On error, raise an IOError with message string, not a raw string exception as in the initial code
