Bug #2356

Updated by skyjake over 4 years ago

* Failure to parse Map Infos in DD_DEFNS of Sigil v1.21. The DD_DEFNS says it uses version 5 syntax, but it lacks the required semicolons. The semicolons are not strictly needed, so they can be made optional for the parser. ☑️
* Music definitions are missing. Should look up by lump ID instead, if no definition found. ☑️
* In the intermission, the labels "Entering" and the next map name are fully overlapping each other.
