Cmake

Discriminator,

I've made a few changes to your source code, that you are welcome to pull into your main repository:

- I added files to generate Visual Studio projects with cmake (in order to use alternate version of Visual Studio)
- I fixed some deprecated coding techniques so it would compile with Microsoft Visual Studio 2012.
- I fixed a iterator overrun that causes a crash when dragging around filters in the filter window
- I fixed a buffer overrun that occurred when parsing POCSAG messages
