Add config option to set initial admin password

There are various contexts in which it would be advantageous to be
able to set the default admin password initially in the config file.
This commit provides that option while retaining the default
behavior of setting the password to "admin".
Fix for translating dynamic enumeration values containing periods.

Since these are effectively user-supplied, we need to make sure we don't
blow up when users (rightly!) add punctuation characters.
Fix click on combobox scrollbar causing list to close
Correct handling of defaults when translating enumerations.
remove an unnecessary initializer

record context. Therefore make the language more generic.
minor tweak to EAD exporter
refine mixed-content hints
loading nested records hit the db in a weird way ( SELECT * FROM  WHERE ( != ) )  if there are not associated values. This causes table scans and really sucks. only perform the #each if there's actually something that needs to be loaded..
