JSONSchema Validation For Filters

[pik]

• Errors are now raised for invalid filter properties
• Easier to test / human-readable (compared to the for-loops from before)
• Adds invalid filter tests

Also the that the room_event_filter schema supplied by the spec does not actually function in all cases e.g. ##1782 - should probably be addressed, adding test cases and either by adding the missing functionality or limiting the schema.
