Match Box Topology to Tortoise
avoid a small bit of duplication with Scala standard library
DRY up project/FastMediumSlow.scala
slight build simplification
remove a line of unneeded code

hasn't been needed since we moved checksums.txt out of the models repo
and back into the main NetLogo repo
update .gitignore
read the language tests as resources

this is for Tortoise; over in the Tortoise repo, we'll be using
this same code to read the test files out of NetLogoHeadlessTests.jar

in conjunction this, move /resources/ to /resources/main/, and move
some stuff out of /test/ and into /resources/test/, to mirror
the organization of /src/
update 'sbt depend' for Reflections library
language tests: Tortoise needs access to the Fixture name
oops missing piece of last commit
revert last 2 commits, I found a better way

Merge pull request #510 from NetLogo/headless-tortoise-box

Match Box Topology to Tortoise
trivial code improvement
latest sample-scala extension (build uses sbt 0.13 now)
fix accidentally duplicated code in headless.lang.Finder

looks like a mistake I made during refactoring -- redundant nested
calls to withFixture

it was a hell of a ride figuring out that this was this root cause
of problems I was having downstream in the Tortoise language tests.
Merge branch 'headless' into sbt-0.13.1
