Modified Get{BYTE,WORD,DWORD}() to return the respective type 

Having e.g. GetWORD() return a WORD rather than int eliminates the need for
a cast when assigning to WORD variables. We use casts only when assigning
to a different (but same-sized) type.

Also, check for EOF explicitly when calling fgetc().
