Convert compile demo into a unit test. (#1360)

* Intentionally break Travis.

* Alphabetize tests, remove orphaned test, and add fail to test that's running.

* Unbreak test, disable OS X, move scripts, list compiler directory.

* Test Java, break test.

* Unbreak test, call compile script.

* Compile main_compressed.js

* Run test command using bash.

* Fix path.

* Exclude node modules.

* Be more specific about JS files to compile.

* Test failure.

* Restore OSX, undo Blockly failure, remove compilation demo, add compilation test.

* Delete manual test files.

* Ignore downloaded/generated files.

* Whitespace cleanup.
