Subject: [PATCH] [Assets] Allow scripts to override assetRoots

Summary:
The CLI parse was accepting a string but assetRoots should be an array, so split on commas. Tested by specifying a root directory that was at least two folders up (../../stuff).
Closes https://github.com/facebook/react-native/pull/189
Github Author: James Ide <ide@jameside.com>

Test Plan:
* export to open source
* started server passing --assetRoots array
