Inconsistent license variable naming

[Micket]

We currently have a wide selection of license variable names in use. Grepping through the easyblocks we find for example:

LM_LICENSE_FILE
INTEL_LICENSE_FILE
ABAQUSLM_LICENSE_FILE
EB_MATLAB_LICENSE_SERVER
LMCOMSOL_LICENSE_FILE

so, it's either

• LM_xxx
• NAME_xxx
• NAMELM_xxx
• LMNAME_xxx
• EB_NAME_xxx

I was going to suggest to stick to just one pattern:

EB_NAME_LICENSE_FILE
EB_NAME_LICENSE_SERVER
EB_NAME_LICENSE_PORT

Doesn't really need to wait for 5.0 i guess, I'll just change COMSOL to use this syntax to reduce the variations a bit as a start. #3044
