It's hard to believe, but this fixes bug "#10432" WME Carol Reed
Mysteries hint system not working.
Carol Reed hint system happen to heavily use line.Split(";") results,
which were wrong by 1 byte (delimeter was appended to result while it
shouldn't be).
I started with decompiling Carol Reed source code, reproducing issue
with a stand-alone test project (which worked with WME and showed [null]
with ScummVM). then minimized it to a minimal testcase:
var line = new String("New Goal;Visit Christina at the Art
Museum;1;0;S;;");
var ar = line.Split(";");
if((ar[0] == "New Goal")) { var g = ar[1]; }
This is mostly a lead-up to namespacing the Ad/Base folders, and then
possibly removing the prefixes from the files, it also has the added
benefit of getting rid of the odd case-typos that makes for issues
on platforms that don't ignore case.
