Reformulate naming convention. Add global configs.

hybrid.sub is created to add hybrid numbers to file, avoiding having to define that in st.cmd file. Similar thing is done for VMM chips, since it's always going to be 2 per hybrid.

Add global configuration values. Global PVs should configure all parameters for all VMM FENS, without need of knowing the topology. This is done by loading a global configuration file that has the options, and adding - in each template file - records that take the value from global and pass it to the particular record. For example:

global-something.template file has a record called G:Yeehaw something.template has a record called VMM-0000:Yeehaw and a record called VMM-0000:#Yeehaw #Yeehaw get the value from G:Yeehaw and passes it to VMM-0000:Yeehaw.

Channel global configurations need to connect to asyn port in order to correctly initialize the array record, because EPICS is weird :(
