first pass at status module (wip)
Merge tag 'server-v0.7.6' into develop

Release of version 0.7.6
prevent deletion of resources that use common-rest if the resource has an external reference to it
remove ignored tests for external refs from APIs that rely entirely on common-rest and have no other unique mode of reference (idno)
reference index should track references to users in changelogs
api:rest-error() can also return info messages
api error namespace
user deletion + tests
Merge branch 'feature/deletion-apis' into develop
Merge branch 'develop' into feature/background-compilation
add status logging to the compilation process
record status with a job number
remove old jobs module
job-id should reference the document being compiled
tests for the status module
base the status module on job-id, not original-doc as the primary key to call functions
bugfix: reference index is not indexed due to missing xmlns
new range index caused a fail in the syntax used in refindex
first pass at background compilation (no tests yet)
multiple-string searches needs to be phrased this way, class fix
