Advanced Rogue 7: fix a string literal overwrite.
pick_spell() attempted to capitalize type by overwriting the first
character, changing it back later. All calls of pick_spell passed a
string literal as type, and string literals should be considered
immutable.
This has been fixed by using a separate variable for the capitalized
first character. XRogue already has a similar fix.
