* Added names to the SC_ and SI_ enums, now they can be used to properly indicate where such values are to be used (replaces usage of 'int')

* removed MIN_/MAX_PORTAL_MEMO, set MAX_MEMOPOINTS from 10 to 3
* removed support for @go-ing to your memo points
* simplified the overly verbose @memo command; now re-uses pc_memo()
* cleaned up pc_memo(), now uses semi-correct packet replies
* Minor code cleaning/formatting

 IF YOU HAVE A WORKING AND TESTED BUGFIX PUT IT INTO STABLE AS WELL AS TRUNK.

+	* Added names to the SC_ and SI_ enums, now they can be used to properly
+	  indicate where such values are to be used (replaces usage of 'int')
+	* removed MIN_/MAX_PORTAL_MEMO, set MAX_MEMOPOINTS from 10 to 3
+	* removed support for @go-ing to your memo points
+	* simplified the overly verbose @memo command; now re-uses pc_memo()
+	* cleaned up pc_memo(), now uses semi-correct packet replies
+	* Minor code cleaning/formatting [ultramage]
 	* Updated several mapflags - 'nomemo' 'noteleport' 'nosave' 'nowarpto'
 	  'restricted' - due to Izlude Battle Arena release. [SinSloth]
 	- Updated 'item_noequip' and 'skill_nocast_db' to match with 'restricted' mapflags.
