Insteon_TriggerLinc: Add Initial Support for TriggerLinc Devices

Basically just a copy of code for RemoteLincs, however, TriggerLincs support even fewer commands so much of the code was cut down.

I put the code in the Security.pm file as these are ostensible security devices, however as noted above, these are very similar to RemoteLincs.  Although, they are not that dissimilar from Motion sensors which are also in this file.

I don't own a TriggerLinc so this coding is all done blind.

Thanks to @JaredF for his testing work.

Closes #245
Merge pull request #270 from krkeegan/insteon_triggerlinc
