Create Standalone release for Windows, OSX, Linux

[bastianilso]

In preparation for the upcoming RTII course, we want to distribute the ArduinoLogger as a standalone app, which the students can run on their own computers, as have been done in the past.

For this release, we will need a few things:

• Update the READMEs of the ReactionTime/SynchTest Firmware and EDA-IBI-Serial firmware with step-by-step instructions on how to use them with the ArduinoLogger (including screenshots and highlighting what button to press on arduino and/or what sensors are in use). Include a link which the students can use to check the R Shiny Data. Emphasize what to do if something goes wrong (e.g. make sure you are on the AAU Wi-Fi). See a reference step-by-step guide used last year here. and here.
• For the SynchTest/ReactionTime instructions, we need to explain how to change between ERM/LED and how to set MusicalAbility (to values HIGH or LOW).
• Assign the ArduinoLogger a new version number and write a short list of what changed. Export from Unity to OSX, Linux, Windows.
• Test the exported versions on the respective platforms, with the different arduino firmwares and check that the data gets sent to the database and can be found in R Shiny.

Additionally when releasing, create a commit which updates the ArduinoLogger README indicating which version is the latest and linking to the release page.

the Mac release on the previous release doesn't work.

@MaximeHollebecq it should work - it was tested before it was released. If it doesnt work now, it may be because OS X updated or similar. What parts about it exactly doesnt work? Are you able to make a working Mac release from master?
