fix edje error reporting for once and for all.

fix edje error reporting for once and for all.

edje error was a mess. First someone (maybe myself) added eina log,
then people changed it to be a mix with printf()... then they replaced
eina_log with printf() + colors so it would be less verbose.

It's fixed now! Using eina log infrastructure.

If all that is wanted is specific messages for edje_cc domain, do it
with a specific log print function (eina_log_print_cb_set()). I made
it produce messages in the format:

    <levelcolor><progname>: <levelprefix><message>

Where:
 - levelcolor is defined by eina_log (I hacked the win32 version,
   since no public api to resolve level to color).
 - levelprefix is "Error. " or "Warning. " to cope with traditional
   output.

If it does not look as you wanted, let me know before stuffing some
printf() again.

Bonus point: reduced 2 global variables (progname and verbose),
removed lots of code.
