Resolved Issues #5 and #6

5. The check for available spell points only uses the lower 8 bits. So a
magic user with a power of 2 number of spell points > 255. (256, 512,
1024, etc) would not have the option of casting a spell. Replaced that
with a check for zero on the spell points.
#6. A case of having a local label the same name as a function name.
Renamed the convertToGeomancer label to l_convertToGeomancer.
