First-pass jnius conversion
Reverting for beta2

-Update importer with API changes in beta 2
-Temporarily disable equipment setup in test (failing one test), until
beta3's rename of setEquipmentSetupWithMap
Most tests passing under jnius
 Move all the casting to __main__
OK, never mind
Add DateTime import
Upgrade to neo 0.3.0 and Windows

Windows tests pass, except for equipment setup and a new regression
related to signal.annotations['channel_index'], possibly neo 0.3.0
related. Check this on OS X
