Add jsx:test task to defaults

[maxwellpeterson-wf]

Fixes #110

Problem

The supported 'jsx' language option does not come with a default task that will transpile .jsx in ./test to ./build/test

Solution

Add new default task jsx:test

How to +10

• Include a .jsx file in ./test
• gulp test should result in that file being transpiled into ./build/test with a .js extension
