README: change optional limit-removing to vanilla-compat only

Browse source 
As with the prior README commit, this doesn’t actually mean Freedoom
is 100% vanilla yet, but we should be making it a hard goal at this
point.

=== Levels
Levels for _Phase 1_ and _Phase 2_ must be compatible with any limit
removing engine. This means that you may exceed the limits of the
original _Doom_, but do not depend on any additional mapping features.
Levels should be in _Doom_’s original format, not in “Hexen”-format.
It is a goal that future versions of _Freedoom_ will be entirely
vanilla-compatible, not even allowing expanded limits. Keeping this
in mind while mapping may make it easier for your level to be
preserved. Levels requiring large amounts of modification to fit into
vanilla limits may be discarded entirely in favor of a less complex map.
Levels for _FreeDM_ must strictly be vanilla-compatible, that is, they
must run in the original +doom2.exe+ engine for DOS and not cause any
visplane overflows and other such problems in the vanilla engine.
This ensures the maximum compatibility with all _Doom_-derived
engines.
All levels for _Freedoom_ must be vanilla-compatible, requiring an
expanded-limits or limit-removing engine is not permissible. This

* While unrestricted by limits, do not make excessively complicated
scenes. It is desirable that _Freedoom_ levels should be playable
on low-powered hardware, such as phones and old computers.
* For _Phase 1_ and _Phase 2_, try to test your levels in
http://fabiangreffrath.github.io/crispy-doom[Crispy Doom], which
is an engine that is limit removing but does not introduce mapping
features to accidentally exploit.
* For _FreeDM_, while you can test in the original +doom2.exe+
engine with DOS or an emulator, this original engine is not free
software and not legally obtainable without _Doom_, in addition to
the hassle of merely running it.
http://www.chocolate-doom.org/[Chocolate Doom] is a free software,
highly-portable, and strictly vanilla-compatible engine without
any extra features for levels, suitable for testing FreeDM.
* Test your levels in https://www.chocolate-doom.org/[Chocolate
Doom] to make sure that vanilla compatibility is maintained. This
is an engine with strict adherence to vanilla Doom limits and bugs
and working it assures that levels can be played with any _Doom_
engine.
