Summary:
We can add `GRANULARITY_DIRECTORY` and `GRANULARITY_REPOSITORY` later.
Repository granularity may use current commit + changes.
Directory would need to use hashes of all files in dir which would be quite expensive.
Test Plan:
$ echo '<?php class A extends B {}' > A.php
$ arc lint --cache 1
$ arc lint --cache 1
$ echo '<?php class B {}' > B.php
$ arc lint --cache 1
$ arc lint --cache 1
$ rm B.php
$ arc lint --cache 1
$ arc lint --cache 1

Summary:
SBT is the most common Scala buildsystem. This adds an extremely basic and
slightly horrible linter to check SBT's output for warnings and errors.
Test Plan:
Tested this with a Scala project I've been working on for some time.
It seemed relatively sane.

Summary:
There is one big decision: How to get linters version.
I've created `getCacheVersion()` which is supposed to be bumped every time engine or any linter is changed.
This is not very nice but the other alternative (detect this automatically) seems worse:
- The engine may be outside repo and may or may not be under version control so getting its version through something like `git log` may not be even possible.
- If it is in the same repo then every rebase will obsolete the whole cache.
Even though bumping the version manually is PITA I still think it's a better solution.
Test Plan:
$ time arc lint --cache 1
# verified file
$ arc arc lint --cache 1
# added some debug output to see the cached results
# also observed better time (.57 s instead of 2.19 s)

Another solution would be to extend `ArcanistLinterTestCase` from `ArcanistArcanistLinterTestCase` and return null in `getLink()` to avoid code duplication but I prefer clean class hierarchy.

Summary:
This commit doesn't change license of any file. It just makes the license implicit (inherited from LICENSE file in the root directory).
We are removing the headers for these reasons:
- It wastes space in editors, less code is visible in editor upon opening a file.
- It brings noise to diff of the first change of any file every year.
- It confuses Git file copy detection when creating small files.
- We don't have an explicit license header in other files (JS, CSS, images, documentation).
- Using license header in every file is not obligatory: http://www.apache.org/dev/apply-license.html#new.
This change is approved by Alma Chao (Lead Open Source and IP Counsel at Facebook).
Test Plan: Verified that the license survived only in unit tests and LICENSE file.

We want to have a class of lint problems which are displayed to author and attached to revision but don't require excuse in diff workflow.
Lint advices already serve this purpose but no linters emit them because they need `--advice` flag to be processed.
By always enabling advices, we can switch more linters from warnings to advices and don't stop the diff workflow for them.
This diff also bumps down default severity of TODO rule.
