reorganisation of directories

In this MR the directory GUI/coregui has been removed and the containing source code has been moved into the parent directory. (See #63 (closed)).

The moving of the files and the readjustment of the include directives was made in two steps because that way git was able to track the files. So the commits contain the following actions:

1. commit: moving of files only
2. commit: adjustment of the include directives only
3. commit and following: changes to the build system and other small improvements

Looks good to me - of course without checking all the 972 changes ;-).

@j.wuttke, since you created #63 (closed): Maybe you want to take a look whether this meets your expectations? I didn't approve only for this reason.

Just remembered from the talk we just had that I forgot to fix the include guards. Will supply that in a moment.
