Some operations modify the options object, which could influence the next
test set.
Modified the test labels in the output to include the
folder (to distinguish between the normal and BOM tests).
Modified warning message from data-uri file-not-found to include the
filename.
Modified tests to run against a copy of the test files with BOMs inserted
into each .less and .css file (the copies are generated automatically if
the /test/less-bom folder doesn't exist or is empty).
This patch adds Support Map Tests to the rhino test suite. It makes the
following changes:
1. Fix typo in the Gruntfile.js for the sourcemap-test
2. Update Gradle build to always build the less-rhino-<version>.js
before running the tests
3. Add a new testRhinoSourceMap and add it to the test list
4. Add a SourceMapRhinoTest that bootstraps SourceMap tests and then
validates them after they run
5. Add hooks in RhinoTest to support custom bootstraping and validation
6. Add compiled version of source-map (version 0.1.31) because Rhino
can't dynamically pull in dependencies
7. Add source-map to the Rhino build with a Header/Footer that wraps
source-map as a less-friendly dependency
8. Update lib/less/rhino.js to properly handle (some) source-map options
and add a new one (--source-map-output-map-file) that will output the
source-map to a separate file (so we can validate our Rhino tests)
9. Remove unused callback in less-test.js
