A web service to remotely control the presets over HTTP from e.g. a smartphone. Screenshot:

Usage:
[HTTP_PORT=<HTTP port> [HTTP_NAME=<HTML title>]] ./projectM-jack

Requires LibQxt. Unfortunately, cmake doesn't come with a FindQxt.cmake yet. I modified the one available at
http://dev.libqxt.org/libqxt/src
in the folder "features" to work with Ubuntu 12.10:
http://sven.killig.de/projectM/FindQxt.cmake
Put it to /usr/share/cmake-2.8/Modules

I first tried to start my web service in projectM-qt, but somehow it didn't work, so for now it's only available in projectM-jack. Perhaps someone more experienced with Q[x]t can fix this.
