Suggestion box in GenStat!

Dear PR responsible,

First of all... sorry, this got bigger than expected. This PR adds a page Suggestion Box to Genomics Status, that replaces the Google Docs form.

Secondly, I removed old code from Amanita and Picea pages, as well as some references to other databases that I'll remove when this gets merged in production.

Notes about this PR:
* This is the work around for: https://trello.com/c/bG9yVkaZ/328-new-turn-to-the-suggestion-box
* The files `jquery.validate.js` and `spin.min.js` are javascript plugins that you **do not** need to review.
* Below some screenshots, but it is deployed in https://genomics-status-stage.scilifelab.se as well so, feel free to find bugs, I'll be happy to fix them. Everything will go to tools-dev, that I'll wipe out once this gets merged, as well as the trello board.
