Summary:
This commit will add some API for working with aliases.
There are four functions will be added:
1. edje_edit_group_aliases_get - this function will return the list of aliases of certain group.
2. edje_edit_group_is_alias - this function will check if the given group name is actually an alias.
3. edje_edit_group_aliased_get - return the main real group that is being aliased.
4. edje_edit_group_alias_add - add new alias name.
Also the function "edje_edit_group_del" was modified because of wrong behaviour.
Now if the given group is alias, it will successfully delete it,
but if the given group is main group, it will also delete all it's aliases.
This commit also modify EDJ file by adding new field for detecting if the group is alias or not.
