Make default configuration settings consistent with module behavior

The variable_get defaults for securepages_pages in securepages.admin.inc includes the path 'user', however the variable_get defaults for securepages_pages in securepages.module does not. This will give the impression that the module is not working correctly on the url http://www.example.com/user. Once the user has saved the settings, the variable_get pulls the same value from the database in both places and so becomes consistent.

I have written a small patch to solve this issue. It uses the define() to create constants that hold the default values for securepages_pages and securepages_ignore. These constants are then used for the default values in the variable_get() calls to ensure that there is no difference between what is shown to the user and what is used internally.

Additionally, I have modifed the 'user/*' path to be 'user*' following the patter of 'admin*' This provides protection by default at /user as well as user/login, user/1, etc. with a single config line. Comments are welcome.
