First-Run Assistant: Set file filter to backup file chooser
ISSUE: Once the user has decided to use an Evolution backup file, the user does not necessarily know they are in a file navigation window and would not necessarily know what a backup file would look like. What would the file suffix be? New users (or maybe even other users) do not know, so locating a backup file would be difficult.
RESOLUTION: Change the text in this window to "Find backup file (with .*** sufffix):" where *** is the backup file suffix. The suffix would help the user find the backup file, and the verb "Find" lets the user know they are looking for something, which makes it easier for them to realize they are navigating the file system for a backup file.
