Some changes for references / logging to a text file / how to build uitools

[Hecatron]

Added a couple of small changes, not sure if you want to add all of these in but some might be usefull

• Added a couple of missing references to QtSharp.CLI for Compression
• Added Nuget packages subdir to .gitignore
• Added a simple console redirect for logging to a logs subdirectory for each module
• Added a doc on building out uitools

A better option for logging might be something like common logging https://github.com/net-commons/common-logging but that would require lots of changes to CppSharp, so the above changes just redirect the console to a seperate log file for each module

I actually meant for you to amend your commits, not apply new ones on top. I know this would cause you some trouble with rebasing but I'd rather have the commits clean in the first place instead of being fixed afterwards.

[Hecatron]

Okay no probs I'll probably just re-fork the repo and redo the commits, I didn't know you could ammend commits afterwards

[ddobrev]

Well, you don't actually need to, just amend/rebase/etc and then force push.

[Hecatron]

yep that's what I'm going to do, I just didn't realise you could rebase an amend commits before now
