Expanded script command setbattleflag

* Fixes #1945.
* Adds an optional flag to reload the monster database for specific map flags that are EXP/drop related.
* This resolves having to add atcommand reloadmobdb after setting the battle configs.
* Adjusted atcommand setbattleflag to also have the optional parameter.
* The reload should only have to be called on the final setbattleflag use.

 Sets or gets the value of the given battle flag.
 Battle flags are the flags found in the battle / *.conf files and is also used in Lupus' variable rates script.
+If the reload value is given then the server will attempt to reload monster data
+to properly apply the new rates. This applies to EXP/Drop type configs. The server
+will only attempt to reload specific configs.
 
 Examples:
 
-// Will set the base experience rate to 20x (2000%)
+// Will set the base experience rate to 20x (2000%) - Monster data will continue to use previous rates at server start
 	setBattleFlag "base_exp_rate",2000;

+// Will set the base experience rate to 20x (2000%) - Monster data will be reloaded to new value
+	setBattleFlag "base_exp_rate",2000,true;
 	
 // Will return the value of the base experience rate (when used after the above example, it would print 2000).
