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)

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.

Summary:
When some linter throws then we don't print any result.
This is bad in case when the linter threw e.g. because of syntax error in some file which some other linter will tell us about.
Test Plan: Threw from a linter, made lint error in a file, saw error then exception.

Summary:
We have a lint rule checking if some string is too long.
This string can span multiple lines.
If we report a warning at the first line then it is muted if the first line wasn't modified.
We need to say that this whole block is wrong and report it when at least one line from the block was modified.
Test Plan: Changed a lint rule to call `raiseLintAtLines()` and verified that the warning is reported even if the changed line isn't first.

Summary:
This uses a similiar approach as with postponed unittests, allowing
the lint workflow/engine to report postponed linter names. After
the lint engine is run, a separate method is used to collect any
postponed linters and these are reposted to the diff via the
"arc:lint-postponed" property.
Also, a ##diff.wasCreated## was added allowing hooks to be called
immediately after the call ##differential.creatediff## with the
returned diff ID.
Test Plan:
Created diffs with a dummy lint engine which always reports a
postponed linter.
