diablo: rename spszMsgTbl and spszMsgKeyTbl to NetMsgStr and NetMsgHotKey

Rationale described in sanctuary/notes@3cd6417cdfafba340145939c2054ec614e1bd33e
as included below:

Infer the name of NetMsgStr and NetMsgHotKey from the
PSX debug names of:

	char *PanBtnHotKey[8];
	unsigned long PanBtnStr[8];

Note, the previous use of spsz hungarian notation has been removed
since searching for "spsz" gave no results in the merged output of
PSX debug info: https://github.com/diasurgical/scalpel/tree/master/psx/_dump_/_dump_merge_c_
