Recording fixes for BBB 2.2

It was previously trying to get the presentation name from the wrong variable,
which resulted in a nil value (which was treated as a blank string in
filenames). This caused the poll images to not be inside the presentation
subdirectories, and the poll image references in the svg contained a `//`
path, which would break the recording if it was uploaded to e.g. AWS S3.

/mnt/tmp/bbb-transcode-akka_2.2.0_xenial_m22/build.sbt:134: error: object ServerLoader is not a member of package com.typesafe.sbt.packager.archetypes

 - fix akka-transcode build failing on scalariform

This fixes font scaling in the presentation area, since that relied on
the <p> element inheriting the font size from the svg <g> that it was
inside of.

This was broken with the switch to the Foundation stylesheet base, which
set a fixed font size on the <p> element.

Fixed locked user to have the same height as a default user

Adjust the presentation upload to use the security token introduced in 2.1
