Subject: [E-devel] Provide sensible errors for edje utilities

If you start edje_player or edje_inspector with a path to a file that doesn't
exist you get a bogus error message saying that the file doesn't contain any
groups. The attached patch uses access() to check if the program can read the
file, giving a sensible error message if not.

I have checked the other utilities there, too, and they work, with the
exception of edje_external_inspector. I'm not sure how this one works at all,
but it seems not to take a file but a list of modules, maybe someone with
greater insight can take a look at that.

Going through things installed under bin, I'll take a look if those behave
properly and create patches for those, too, if this one is okay.
