Jnygaards auto proxy test

Added GUI-elements and code for autoProxy enabling. This requires a new version of Tinia, with autoProxy support in it. (There is a pull-request for this, not yet accepted.) Without such a version of Tinia, nothing breaks, but the autoProxy feature does nothing.

The autoProxy-settings are recognized by Tinia listening to a set of exposed model elements, all of these are prefixed with "ap_". If another way of interfacing with this is preferred, it is suggested that this is entered as a bug or enhancement issue instead of blocking the pull request, if there are no other problems.
