Release Notes 0.3.1

Hydra 0.3.1

This release brings some needed build improvements, as well as bug fixes and new features.

SLF4J implementation conflicts. 0.3.0 had some problems with conflicting versions of slf4j implementations, causing stages to crash. That is now fixed, and the only implementation of slf4j comes from API.
The built Core and resources file is now placed in distribution/bin.
Configuration for SetStaticFieldStage has changed. It now takes a Map<String, Object> called fieldNames instead of two lists.
It is now possible to use Enum parameters for stages. Both string and int vaues will be converted to the correct Enum value.
Documents with binary attachments can now be inserted using the database package, without risk of race conditions.
Inserting too large documents into Hydra is now safer, but they may be truncated.

Switch Hyra Core (if building it yourself, remember to pick the one in distribution/bin.
Rebuild stages with 0.3.1 API to ensure only one version of the logging framework is present.
If using the SetStaticFieldStage, update the configuration with a Map instead of the two lists. The map is called fieldNames, which replaces the lists fieldNames and fieldValues.
