Sometimes has-one UploadFields can get confused about whether or not there is an existing file that needs deleting. This setting lets you make a more robust has-one UploadField, where any existing file will be replaced. It more closely mimics simple single-file upload fields.
This is the companion setting to canUpload, letting you control whether existing files from the asset store can be referenced. It's particularly useful when using UploadField on the front-end.
Although editing meta-data or deleting permanently would require File editing/deleting permissions, merely linking to a record does not. This change is important for allowing front-end use of UploadField; or, more importantly, use of UploadFile by people without CMS rights.
The field carries the configuration, and some non-upload functionality
like "attach files" still relies on the fileupload jQuery plugin
being initialized.

Needed for introspection for many_many relationships
without knowing the name of the relationship,
meaning we can't use DataObject->many_many_extraFields().
Otherwise conditional logic will only succeed
when run through "sake dev/tests", not when
run through phpunit directly (which is the recommended way now)
In certain cases, the button may not yet be initialized or may no longer have button properties at the time of removal from the DOM. Without this check, an uncaught exception is thrown.
+ has a special meaning in the URLs so overall it's a good idea to
strip them out. Otherwise they would need to appear in their ugly url
encoded form "%2B".

Although PGSQL build will still be executed, a failure of that build won't registre as a Travis failure. This is a workaround until the PGSQL build has been fixed.
Session is not initialized by the time we need to use
the setting in DB::connect(). Cookie values get initialized
automatically for each request.
Tightened name format validation to ensure it can only
be used for temporary databases, rather than switching
the browser session to a different production database.
Encrypting token for secure cookie usage.
Added dev/generatesecuretoken to generate this token.
Not storing in YML config directly because of web access issues.
Backport from master. Fixes display issues with expanded,
unselected submenus ... by removing them.
They're strictly not necessary since both "list" and "add"
modes can be reached through the default AssetAdmin UI.
