Branch auto-selection in additem

Branch auto-selection in additem

Adding a new item should pre-select the library you are logged in at, where possible.
Use GetBranchesLoop.  This solves indy branches filtering, and sort order problems.
Set default off of ->{selected}, to establish pre-selected branch.
Fix flags check in onlymine sub, so superlibrarian + other flags still gets everything.
Removed defined(@array) check, since perl -wc warns it is deprecated.
Note new FIXME for botched date processing.
