2.0.1

Bugfixes:

• Using cy.contains() with a RegExp argument is now properly escaped. Fixes #1322.

• Fixed a runaway RegExp causing large .js files to take dozens of seconds to process. This was a regression caused by 2.0.0 with the new modifyObstructiveCode option. We've optimized the RegExp and the performance is back to being almost identical to transparently passing responses through. Fixes #1330.
