Remove spec support from converter

Browse source 
Khronos stopped supporting .spec files in 2013. They're now over a year
old without support. As such it's not worth us continuing to support
them either.

[Usage]
Convert.exe -p:{PREFIX} -v:{VERSION} -t:{TYPE} -o:{OUT} {INPUT1} ... {INPUTn}
{PREFIX} is a simple string that defines the a common prefix for functions and constants in this header. This prefix will be removed from the generated XML file.
{VERSION} is a string that defines that version that will be used for functions in the generated XML file. Specific input files may override this setting.
{TYPE} can be either 'spec' or 'header' to indicate whether the input files are OpenGL .spec files or C headers.
{TYPE} can be either 'xml' or 'header' to indicate whether the input files are OpenGL .xml files or C headers.
{OUT} is the output filename (optional). If no output file is specified, output will be directed to the console.
{INPUT1..n} is a space-separated list of input files (headers).
Despite what the help says, all three parameters are necessary at the moment.
