 -------------------------------------------------------
 == 02/26/2017 ==
 Uleat: Moved bot `npc_spells` entries from '701-712' to 3000 + <class_id> .. also, added melee types for future expansion
+Uleat: Moved bot spell casting chance values into database - this will allow admins to tailor their bots without having to rebuild server code
+	- Each entry uses a 3-dimensional identifier: [spell type index][class id][stance index]
+		- [spell type index] is not the SpellType_## bit value..use SpellType_##Index instead
+		- [class id] values of 1-16 are valid and hold a direct correlation to server-coded player class values
+		- [stance index] is a direct correlation (0-6)
+		- the 'conditional fields' are currently predicated on 4 compounded boolean states:
+			- `pH_value` represents bit '0'
+			- `pS_value` represents bit '1'
+			- `pN_value` represents bit '2'
+			- `pD_value` represents bit '3'
+			- all other conditional fields are masked based on these 4 predicates
+		- the full conditional field enumeration is as follows:
+			- `nHSND_value`		- negative Healer/Slower/Nuker/Doter
+			- `pH_value`		- positive Healer
+			- `pS_value`		- positive Slower
+			- `pHS_value`		- positive Healer/Slower
+			- `pN_value`		- positive Nuker
+			- `pHN_value`		- positive Healer/Nuker
+			- `pSN_value`		- positive Slower/Nuker
+			- `pHSN_value`		- positive Healer/Slower/Nuker
+			- `pD_value`		- positive Doter
+			- `pHD_value`		- positive Healer/Doter
+			- `pSD_value`		- positive Slower/Doter
+			- `pHSD_value`		- positive Healer/Slower/Doter
+			- `pND_value`		- positive Nuker/Doter
+			- `pHND_value`		- positive Healer/Nuker/Doter
+			- `pSND_value`		- positive Slower/Nuker/Doter
+			- `pHSND_value`		- positive Healer/Slower/Nuker/Doter
+	- Single- and mixed-bits fields should be filled-in based on the boolean 'AND' concept
+		- (i.e., if 'healer' then `pH_value`=x; if 'slower' then `pS_value`=y; if 'healer' AND 'slower' then `pHS_value`=z; )
+		- most cases can allow the same value across all fields..but, there are some that shouldn't and this format allows for their discrimination
+	- Valid `##_value` entries are 0-100..though, the field accepts up to 255... Anything above 100 is clamped to 100 upon loading, however...
+	- Not all conditions are currently coded and changing a field may not produce any results
+	- The 'default' database values will be changed and tweaked as bot spell code modifications occur
