update bin/issues.scala on master to point to 5.1 milestone on GitHub
fix build script regression where extra junk was ending up in extensions dirs
update instructions for running bin/issues.scala to work with sbt 0.12
convert prim._constlist to Scala
convert _link/patch/turtle to Scala
relocate AppletTester to org.nlogo.tools

since it's not an automated test
sbt: turn off logBuffered for tr/tc/te/tm

because if you're only running one suite it's nice to see
the results as they happen, especially for a long one like tc
relocate some prims from prim.gui to prim.etc

since they have no compile-time dependencies on GUI classes
kill off moribund, undocumented __inspect-with-radius primitive
relocate a bunch of prims from prim.gui to prim.etc

the context is that we want the headless subproject to be self-contained,
but TestAllSyntaxes and TestChecksums and so forth need to know the
syntaxes of prim.gui stuff. either the prims are in the language or
they're not. and they are, for better or for worse.
oops
minor cleanup in sbt build
convert more of AbstractWorkspace to Scala

along the way sorting out inheritance problems causing recent
regression in mouse primitives when running headless
relocate movie prims from prim.gui to prim.etc

the context is that we want the headless subproject to be self-contained,
but TestAllSyntaxes and TestChecksums and so forth need to know the
syntaxes of prim.gui stuff. either the prims are in the language or
they're not. and they are, for better or for worse.
move user prims to prim.etc, kill off prim.gui

relocate all headless tests to headless (now that prim.gui isn't an
issue anymore)
