Whooshalchemy was adding an event every time a new db session was
created, thus increasing a lot the computation time at each new call.
This is now fixed, and is a partial fix for #43.
* Add a database field to store `notes` (as a memo) about flats.
* Add matching UI elements to let users store their notes about flats.
This commit closes issue #34.
* Init Webpack / Babel / etc setup.
* Build the app using Vue, Vue-router, Vuex.
* i18n
Some backends changes were made to match the webapp development:
* Return the flat status as a single string ("new" rather than
"FlatStatus.new")
* Completely switch to calling Weboob API directly for fetching
* Use Canister for Bottle logging
* Handle merging of details dict better
* Add a WSGI script
* Keep track of duplicates
* Webserver had to be restarted to fetch external changes to the db
* Handle leboncoin module better
Also add contributions guidelines.
Closes issue #3
Closes issue #14.
