Add basic implementation for a new meta-tag functionality in the SeltzerCRM system .

    This module is for associating arbitrary "meta data" with member/s.
    This can be useful for making arbitrary groupings of users that have special meaning to you.
    Examples:
    We have one called "Respected", which entitles a member to get a physical key to the building....
    Or one called "Machinist", which means they have passed basic safety assessment to permit them to use our Mill/Lathe.
    It's kinda like an extension to the Permissions system, but for managing things external to SeltzerCRM.
add new meta-tag module to the sample config file.
I realise the Meta-Tags tab user experience was pretty poor.   this is better.
bug fix in display routine ( it was only displaying one checkbox maximum per user , which is wrong).   better now.
hack to force php to a specific timezone… mine.     not for general use as-is, but it gets rid of a php error message.
crm_url second param should be optional.
crm_url needs at least one parameter
mysql_real_escape_string needs to be passed a string not an array.
