Possibility to use a Siemens PLC by multiple different FESA Deploy Units

Currently, the Data Block "_SilecsHeader_hdrBlk" has the same name for each generated *.scl file.

So when loading multiple different *.scl files to the same PLC, the "_SilecsHeader_hdrBlk" will always be overwritten.

That is a problem, since the DB using the Block makes use of its default values, which e.g. contains the "checksum".

This could be prevented by using a unique name for the SilecsHeader-Block. E.g. .. That would even add support for having the same SilecsDeploy deployed multiple times on the same PLC.
