Adding user-select property set to none to the whole container prevents
the accidental selection of the text when panning the panorama

This commit moves all the CSS styles to `/styles` directory and adds a
couple of gulp tasks to generate these styles on prepublish. This
results in having a `/dist` directory being used just for distributing
the package and development. Currently the task has to be run manually
when developing.
