BF: loadFromXML ignores 'componentsFolders' option.

I placed a custom Builder component named 'MyComponent' in D:\work\customComponents and registered this directory to 'componentsFolders' option.
Then, I made a Builder experiment using this component and saved it as D:\work\test.psyexp. When I restarted Builder and try to load test.psyexp, I got following messages.

--------
Failed to load D:\work\test.psyexp. Please send the following to the PsychoPy user list

I think that getAllComponents() in line 340 should receive the value of 'componentsFolders' as an argument to fix this problem.
