Add New Functionality to Paradox mods

[parkerokonek]

Allow for stand-alone files in mod structure or in-line commented out code in otherwise typical Paradox mod files that allow for:

• defining flags/mod presence (DEFINE flag_name, LET a = 0, INCR 0, SET a = 3, etc)
• Making conditionals based off the presence of these flags or values (IFDEF, IFNDEF, IF, ELSE, NOR, etc)
• execute regex or uncomment/comment specific strips of code scoped to certain files or folders (REPLACE orthodox heterodox)

will probably begin lines with commands with ##! as it is sort of a hashbang and shouldn't show up in normal mod files

All flags, values, and replacements will be done based off of load order and will be done at "compile time" when the patch is generated
