Fix imports
Make script timeout configurable (See #12252)

Though this does not handle the fact that there
may not should be a hard-limit at all, but at
least makes the 1 hour limit configurable.
Activate property in servant definition
Adjusted search help hints
Fixed a NPE

Fix for:
https://github.com/openmicroscopy/openmicroscopy/pull/2676#issuecomment-48910713
Workaround for file annotations not being part of annotation index
Caught "TooManyClauses" error
Splitted acquisition and import date column
Corrected some weird whitespace code formatting issues
Correct relative v. absolute timeout

Session creations expect a relative number of milliseconds
to the start of the session itself, while the processor's
expires() method expects an absolute time (since the epoch)
Fixed a travis compile error
