Subject: [PATCH] edje: Edje_Edit - add functions that provide the ability to
 set and get source for proxy parts state

Summary:
This commit contains two new functions that provide the ability to set and get
source property of proxy parts state:
edje_edit_state_proxy_source_get() and edje_edit_state_proxy_source_set().
Also it contains the implementation of printing source data on
edc code generation.
