Bump to 0.4.1

Fix handling of resource bundles and pod subspecs

It turns out that defining the same resource bundle name in multiple
subspecs causes it to be overwritten every time rather than being
additive.

Now, each subspec has its own resource bundle, named for the INKHandler
class it represents; INKApplicationList in turn will only return
applications for a given handler class.
