EntryX is now being used properly.
It is also now being updated after downloading instead of before.
The message uses tags instead of methods for the greeting and signature.
Regular expressions that check for "pdf" are now case insensitive.
Title query now uses the Entry class instead of direct SQL.
The $user variable is now only set by the outer while loop and passed directly
to alert_user().

A custom message is displayed if the user has no papers that can be
automatically archived.
Improved logic for when to display the archiving message and buttons vs.
the message indicating that no papers can be automatically archived.
The behaviour has been tested for a number of cases and looks to be working.
Papers with multiple copies now have a checkbox associated with them.
Archiving only occurs if the checkbox is selected.
A new column to keep track of which papers the user has chosen not to archive
(i.e. rejected).
Added logic to deal with rejected papers. This really should be tested more
extensively, but it looks pretty good so far.
Fixed some ofthe logic for handling rejected papers.

Added a new array reference: $DOWNLOADER_FILETYPES.
This will store the valid filetypes that can be downloaded automatically.
Right now this is only pdf files.
File types and extensions are now determined dynamically instead of being
assumed to be PDF.

New hash for matching Internet media types to file extensions:
%FILETYPE_EXTENSIONS. This is now used by get_file_extension() to return the
proper file extension. It should be easier to maintain going forward when new
file types are considered for downloading.
The query for the filetype has been made compatible with papers that have
multipe copies.
