Secure Wiener write-access with new community name
The new community name for write-access should be read from a file that only the uboonesmc account can read.
The variable definition string in the dbLoadRecords lines in the Wiener "st.cmd" file can have the form
The COMMUNITY epics environment variable can be set from a epicsEnvSet command in the special file that only the uboonesmc account can read, which would be included in the same way "envPaths" is read in the current st.cmd file. The special file with the community name should never be committed to git, and should be kept in a separate directory.
Additionally, with the new organization of the .db files into separate files for input and output channels, we can easily make it so that all the read access is done using the "public" community, and only when values are changed would the write-access community name be used.
The structure described above can be implemented immediately. Actually changing the name will require some configuration of the Wieners.
