#141 Fixed Synergy LIG #add_interconnect

[jsmartt]

Description

See the linked issue for more context and description, but here's the short of it:

1. In #add_interconnect for Synergy LIG, set the correct default enclosureIndex based on the interconnect type
2. In #add_interconnect, for Synergy LIG, set the relativeValue of the enclosure to the given enclosure_index value. This is necessary for LIGs with multiple enclosures
3. In #initialize, for Synergy LIG, set the default redundancyType value (required) to Redundant, like the GUI.

Oops. This will conflict with #140 . I didn't see that PR, so made a few of the same changes. I'll get rid of those real quick...
