Also integrated a basic the tracker Effect with the UI, changed the effect creation to use Json messages, and added the ProcessingController class to handle thread communication
- Parsing from string to Json::Value is now done by utility function
openshot::stringToJson() in Json.cpp, all SetJson() methods call it.
- Expand use of const member functions and args where appropriate.
- Use std::to_string() to format int/float values as strings.
- Correct mentions of nonexistent Json::JsonValue type in docstrings
The range was listed as 0 – 100, but implemented as -1 – +1. Edited documentation to reflect reality.

Fixes#71
* Add ImageMagick 7 compatibility
A new header, `imclude/MagickUtilities.h`, is created to hold the
compatibility `#define`s.
The image-conversion code in `src/Frame.cpp` received the only
major changes — instead of doing the export by hand (and having
to account for changes in the underlying API), it uses the
`MagickCore::ExportImagePixels()` function which does basically
the same work, but accounts for all of the API changes for us.
The API of that function is _unchanged_ from IM6 to IM7.
TODO: `MagickCore::ExportImagePixels()` will return an `exception`
struct if it encounters any problems. Currently the code ignores
that, which it should not.
