Ticket #380: About colors schemes (reopened ticket)

Original message:

If invalid skin name is set via command line (or config file, or environment variable),
then mc starts silently like -b -a mode. Two proposals, if required skin cannot be found:
 *. Show error message "Cannot find skin"
 *. Load the default.ini skin instead of set -a -c mode.

Fix issue:
Mc now more verbose if skin not found:
{{{
_("Unable to load '%s' skin.\nDefault skin has been loaded")
}}}
or if skin not parse:
{{{
_("Unable to parse '%s' skin.\nDefault skin has been loaded")
}}}
Translators: please, update your translates.

Also, mc will try to load 'default' skin before switch to 'b&w' scheme.

This commit adds ability to usage GError - glib error handling.
