[client] added configuration file loading support
the client now will look for a configuration file in the following
locations by default.
* /etc/looking-glass.conf
* ~/.looking-glass.conf
All configuration files are loaded and may override values specified by
any prior configuration files loaded.
Sample Config:
global:
{
fullScreen=false;
showFPS=true;
x=0;
y=0;
w=800;
h=600;
}
OpenGL:
{
mipmap="false";
}
