Add guide to use Qt Creator as IDE

[salkinium]

@rleh has created this really cool guide on how to use Qt Creator as an IDE.

I got this working on OS X, but ran into the following issues:

• The precompiled, official arm-none-eabi-gdb does not support Python scripting, instead arm-none-eabi-gdb-py has to be chosen as the debugger and it is only available since the 4.9 2015q4 release.
• I have a custom PATH, which needs to be manually added to the Kit settings.

Furthermore, I would like to use our getting-started-with-xpcc repo as an example.

PS: xpcc vs. XPCC: the first one is the framework, the second one is the protocol. Yes, I know, confusing.

The precompiled, official arm-none-eabi-gdb does not support Python scripting, instead arm-none-eabi-gdb-py has to be chosen as the debugger and it is only available since the 4.9 2015q4 release.

Ok, on my Fedora 22 and 23 the arm-none-eabi-gdb packages have python support enabled. What about python support in arm-none-eabi-gdb on Ubuntu or Arch?

I have a custom PATH, which needs to be manually added to the Kit settings.

Hmmm, where is PATH used?

Furthermore, I would like to use our getting-started-with-xpcc repo as an example.

I did not know a getting-started-with-xpcc repo exists, but I can adapt the guide. (And fix xpcc/XPCC :grinning: )

Sorry, I dropped the ball on this. I'll work on it this week.

I reworked this to use the getting-started-with-xpcc repository, since that is a "neutral" project that people can actually access.
