Install Hammock
Refactor api_helpers to use Hammock
Refactor send system temp process to use Hammock
With hammock I don't need this
Make separate process to collect system temperature and stash it...

…this is the same pattern used by the indoor temp/humidity process
Move sending of system temp data into main send_data process
Add function to holly utility to send bulk system temp updates from starbug
Don't attempt to send data if there is no data
Make sure I set headers for JSON posts to Holly
This is being handled through periodic bulk updates now...

just like indoor temp/humidity data
add close method to stash
Close stash objects if transmit of data failed
Leaving a note for myself
