Buildsystem refactor and CMake support reimplementation

[DWVoid]

@eidheim I have reimplemeted the cmake support with Codeblocks Project Generators to get more accurate project information. This PR also contains minor refactoring and reformating[I have no exact idea of the project coding style, this PR contains my best guess] Tested with CMake 2.8.12, 3.7 and 3.10.

Thank you, but this PR has some issues:

• Please do not style reformat the source files. I'd like to use clang-format at some point, but its support for lambda expressions is still poor. Also, when we will perform style format on the entire project, we will create and use a separate user account for this, so that no author gets credited for the changes done through style formatting.
• The .idea directory should not be added in your commits
• We use boost.property_tree for xml/json processing
• No need to use polymorphism in the cmake/meson source files. These files are intended to be standalone so that they can be used by other projects. Polymorphish is however implemented in Project::Build instead.
• We do not want to enforce use of a generator like the Codeblocks Project Generator. juCi++ should work on a preconfigured project that for instance have used a different generator.
• There might be other issues as well, but I'm having a hard time reading the changes due to the number of line-changes in this PR.

I am sorry but where is the clang-format configuration file?
