Insteon_Remotelinc: Added Ability to Set Awake Time and To Request Battery Status

The following likely only works for i2cs devices, I think all Remotelinc 2 devices are i2cs?  It at least works on rev 1.4.

- set_awake_time sets = sets the time in seconds that the remote will remain awake after sending a command.  The default is 4, it can be set up to 254 seconds, with 255 being always awake.

- get_extended_info = is primarily added to get the battery level.  Battery level is returned as a byte, but the number does not immediately make sense.  I will have to let the batter run down some to better understand what it means.

At the moment, I have the code set to call get_extended_info whenever the all_link_report is received.  This report represents the last message sent by the device before the awake time begins to run.  In the future, an additional function can be added to only call get_extended_info if it hasn't been called in x hours.

N.B. in order for set_awake_time to work properly, the engine version of the device must be known.
