4 filters

[jliljebl]

Patches add four filters and CMakeLists.txt files for them.

Build files in parent folder are not touched, so to build filters those build files need to modified, for both cmake and autotools builds.

Filters are:

Posterize
Dither
Emboss
Spillsupress

In frei0r, all double parameters must be in the range [0, 1] but I see a comment like this in dither: // range 2 - 50.
and "matrixid = CLAMP(matrixid, 0, 9);" in the code.

So, this is not compliant. See how Marko has done some mapping of ranges in some of his plugins such as select0r. Yes, I know this is a pain, but it is necessary.

Okay, will fix.

I'll send another pull request once I've made code Frei0r compliant.

P.S. I have a commit in my local tree that adds them to both build
systems, and I have done basic compile and execute tests. So, this is
probably the only problem I find.

I have added another commit to pull request that fixes all double
parameters to use input range 0.0 - 1.0, as per Frei0r requirements.

Great, thanks.
