Syndesis: please fix version information in the support button so it is accurate

[sjavurek]

This is a...

[ ] Feature request
[ ] Regression (a behavior that used to work and stopped working in a new release)
[ x] Bug report  
[ ] Documentation issue or request

The problem

When you click on the support button, the version is hardcoded to 1.0. We need this to be correct for GA.

Expected behavior

The correct version is displayed.

For reference this bit also the app name shouldn't be hard-coded either.

It'd be fine to even just bake this into the config.json as far as I'm concerned :-)

[gashcrumb]

Marking p0, think this should be sorted for GA, @paoloantinori wouldn't you think?

[dsimansk]

@zregvart it doesn't look very legit :)

[gashcrumb]

I'll tweak that output a bit...

Thanks @gashcrumb I thought this bit:

would force the Accept header to be text/plain. Obviously thought wrong and when merged on top of #2404 it fell sideways.
