Plugin: showuseragent

Author:  KF  (406man)
Description: Displays the HTTP user agent string 
License: Standard Coppermine
Installation: Standard method.
Version: V1.0   This is the first released version

This is a very simple plugin with just one function - writing the HTTP user agent string sent by the web browser plus 
other relevant information to the "global" log file. Its main use is when debugging user access problems.
When displaying the user agent string it also displays the name of the calling script and the user_id
The advantage of using this plugin are that no changes to the CPG source code (for example to /bridge/coppermine.inc.php)
are needed to display relevant information and it's easily enabled or disabled using the Plugin Manager function.

It’s easy to install and uninstall. There are no configuration options or records stored in the database so there 
are no options for the administrator. Just the standard install / uninstall and enable / disable.
