Categorize and rename MSDOS rule files

Rename many db/MSDOS detection rules to include category prefixes (e.g. compiler_, extender_, immunizer_, linker_, protector_, other_) for clearer organization. Add sLang assignment for Microsoft_C rule to set "C" or "C/C++" based on sName. Normalize formatting/whitespace in several scripts and remove executable bit from a few rule files. No detection logic changes besides the explicit sLang assignment.
