* Fixed "Cursor Positions on Shared Whiteboards are Inconsistent".

The main fix is in the method cursor_point_to_space in
public/javascripts/spacedeck_whiteboard.js.

The calculation of the coordinates of the mouse pointer from absolute
window to the whiteboard space coordinates was incorrect.

There were a number of dependencies on this method which were updated
as a result.

One side-effect was that the div for the lasso tool needed to be
moved inside the div for the whiteboard.

* Fixed minor panning calculation problem.  Works now!

Spacedeck 6.0 CI WIP; more style, UX cleanups; fix account dialog; add more color swatches; new landing page

* The MongoDB/Mongoose data storage is removed in favor of Sequelize. This abstracts over SQLite or RDBMs like PostgreSQL and MSSQL. The default is SQLite, which significantly simplifies deployments in end-user environments.

* As Spacedeck now has no more mandatory server dependencies, we can wrap it in Electron and ship it as a desktop application.

* Removes docker-compose.yml

* First version of import UI
