with my changed code. - Cleaned up DECORATE parser a little - moved the old style parsing code into its own file and rearranged a few things. - Made ProcessStates non-static so that it doesn't need to be passed as an argument to all functions in the DECORATE parser. - Moved DECORATE parser files into their own subdirectory. - Optimization: SC_GetToken no longer sets sc_name for identifiers. In most cases this creates needless overhead by adding a potentially unneeded name to the name table and looking up the name. In almost all cases where a name is needed it's as easy to assign sc_String to the name variable. - Added enum definitions to DECORATE. SVN r537 (trunk)

** Much of this file is fudging code to compensate for the fact that most of
|
|
** what could be changed with Dehacked is no longer in the same state it was
|
|
** in as of Doom 1.9. There is a lump in zdoom.wad (DEHSUPP) that stores most
|
|
** of the lookup tables used so that they need not be loaded all the time.
|
|
** Also, their total size is less in the lump than when they were part of the
|
|
** executable, so it saves space on disk as well as in memory.
