Simpler approach to handling timezones
 - Serializer & Deserializer stop using UTC and just use the default (Eastern)
 - upgrade to sql2o-1.1.12 (DateTime no longer forces a timezone)

Note: several issues here...
 a new version of sql2o is really needed here, (1.1.13)
 a proper database migration script to convert timestmaptz to timestamp is required in stage/production
Use a custom format, not ISO-8601
 - we don't want to include any timezones in what is passed to the web client.  the client simply needs a timestamp, no timezone
Add field event_timezone to conferences table
 - add it to entity, web model, service and queries
Check for new field in `ConferenceServiceTest`
 - incrememnt the version number in the test database builder too
change file name to better structure
 - adjective first, then noun.
 - drop "standard" b/c... it's kind of silly & meaningless here
Change the following fields from `DateTime` to `LocalDate`
 - conference.registrationStartTime
 - conference.registrationEndTime
 - conference.eventStartTime
 - conference.eventEndTime
 - conference.earlyRegistrationCutoff

Also upgrade to sql2o 1.1.13-ryancarlson with support for local time
Tests broken but will be resolved in next commit
convert the 5 fields that are changing to just a timestamp
Add new script to unittest database migration
 update first test
Tests fixed
 - other than registration window calculator test whose class needs more work
that old class name was driving me nuts
Finished correcting rest of tests and code
Add serializers for LocalDateTime and use them
maybe everything (non local) should be in UTC after all
 - prevents jenkins or other environments from arbitrarily choosing a default and getting it wrong

Use the ISO formatter here so that timezone calculations that are required on the front end do take place
Merge branch 'EVENT-45-v2' of http://github.com/CruGlobal/conf-registration-api into EVENT-45-v2
whitespace fixed
PermissionServiceTests should always use UTC times
 - b/c an actual instant in time is recorded
 - eliminate duplicate methods in `JodaInstanceCreator`
Added eventTimezone to transfer tests
Better database migration (easier to run in an IDE)
