Separate OddLOT from remaining repo/tools about covise

[uwewoessner]

We restructured the code which should meke it muich easier now to compile OddLOT without the rest of COVISE and OpenCOVER. If you don't need the feature to drape streets onto a terrain, then you can also compile without the link to OpenCOVER. If you want to go forward and adjust the CMAKE to provide an ODDLOT_ONLY flag, you are welcome.

I didn't know about OpenCOVER, can you tell me where to find more information about it?

The option was already there, just not explicitly documented - which it now is: b7268be
