Send Quip notification messages to OSX notification center

Quip does not notify me about any notifications I receive, so I missed essential messages pretty often. This little app was created to fix that.

What it does

It sends Quip notifications to OSX notification center.

Notifies about direct messages, mentions, and all messages in threads (channels) that are configured as "important".
Delivers all missed messages once the program re-connects, so no messages are missed if a laptop was closed, offline, etc.
Will automatically re-connect if disconnected.
Configurable sound effect.
One notification visible per channel, new messages replace old ones (for the same channel)

Quip format parsing is pretty rudimentary.
Requires some knowledge to install and use it (it's a Ruby app).
This app is good enough for me but no more: this is a quick one-evening project because Quip was giving me rage fits; it's nowhere near production quality.

The app should notify if/when it crashes, loses connection to Quip for a long time, etc.
Find out about token validity. It might expire on me here, and I have no way of knowing when.
Maybe support notification methods other than the OSX notification center?

Clone the repo
Install dependencies: gem install bundler ; bundle
Configure it: Copy config/application.yml-sample to config\application.yml and edit it to your liking. Only an access token is required, other settings are optional, but api_base_url is essential if using on-premises Quip!
Run quip_notifier.rb -d, it should daemonize itself when run with "-d" parameter.
Check logs/quip_notifier.log for more info.
Configuring this app for running upon user login is left as an exercise to the reader.
