Video producer tool using benchmarks in BDV

[mzouink]

I created a tool for video producing using BDV I used the code made by @axtimwalde in hotknife and I embedded it in a GUI. It was a request from @StephanPreibisch

Here is a small tutorial on how to use it: https://youtu.be/vXu4ZOboEio

@mkitti i created a new repo : https://github.com/JaneliaSciComp/bigdataviewer-core-movie-producer in order to have all the changes clear and match to the current version of BDV.
