Use a drop down list when adding exercises to a set in mobile version

The exercise list is not so big that a search box is necessary and
this is easier to use with touch only. This needs to be made more
intelligent if there are many more exercises like e.g. grouping by
category.

Move some JS to external file, hide links to PDF in Firefox OS

Currently firefox OS has no possibility to download authenticated
files, like these PDFs, when using web activities, we can only pass the
PDF's URL to the reader but this will fail, since that application is
not authenticated.
