1.6.4 Release #2

-Fixed a couple typos
-Moved IDs to 20000
-Made it so tools can be repaired by their base material
-Added a creative tab
-Made separate configuration options for each added tool material and
tool type
-Changed the secret items (They're actually sort of secret now...)
-Added New Tool Types (Pax, Shax, & Sickaxe)
-Note: All the textures for the added tool types are currently set to
the old paxel texture, 
 which will eventually be the new pax texture. (I'm working on the
rest.)
