PHPCatalog

Miscellaneous system incompatibility fixes were
made. The documentation was rewritten.

Two problems with some filenames in uploaded files
were fixed. Information for securing admin
directory and more error/security checking in
admin were added. The most common problems were
fixed for .htaccess files that were causing "500 -
Internal Server Error" on some systems if
"Options" was not enabled in Apache config.

A bug in admin the administration section with
select_category that occurred while adding
products was fixed.

The admin was reworked so that the admin directory name can be changed. The phpcatalog_config table schema was changed to key -> value with multiple rows. The format_currency() function and a config value to place the currency symbol before or after price were added. Better checking of requirements was added. gd2 checking was improved. The requirements were changed to PHP4.1. All HTTP_SESSION, HTTP_GET, and HTTP_POST vars were removed and replaced with _SESSION, _GET, _POST, and _FILE to take advantage of PHP 4.1 enhancements.
