remove some obsolete bits from project/Depend.scala
Removing now-false doc comments
Cleaning up literal-parsing regex code
Merge branch 'headless' of github.com:NetLogo/NetLogo into headless
Removing redundant casts
Correcting comment doc variable references
Avoiding '=' on methods of type 'Unit'
Avoiding unnecessary braces on single-item import
Removing unnecessary semicolons in Scala code
Removing unnecessary 'val' modifiers in case class
Removing all things I could find that were both private and unused

All one of them.  There are a ton of supposedly-unused variables, but the vast majority have public access, so... not really safe to remove them.

Undo mistaken changes in f03f899. Issue #320.
(cherry picked from commit d2764b657ab0b286ea2cfa7041ebb54cfca1b179)
Merge remote-tracking branch 'origin/core' into headless
cleanup in BreedIdentifierHandler
Merge branch 'headless' of github.com:NetLogo/NetLogo into headless
fix what seems to me like a minor mistake in BreedIdentifierHandler

can't see a reason the new token shouldn't have the same name slot as
the old token. the name slot is expected to contain the user's original
code, not the uppercased version
cut compile-time dependency of BreedIdentifierHandler on nvm, prim
cut runtime dependency of BreedIdentifierHandler on nvm, prim
relocate BreedIdentifierHandler to parse0

now that its engine dependencies have been cut
