Backport 17516, 17517, 17522, 17523: Allows us to create an /openils/var/web/css/skin/default/register_custom.css file containing local CSS for styling the patron editor.  Example:

TR[fmfield=ident_type] { display: none; } /* be sure to set the ui.patron.default_ident_type setting */
TR[fmfield=ident_value2] { border: solid thick red; font-size: x-large; }
TR[fmfield=barred] { display: none; }
TR[fmfield=country] { display: none; } /* be sure to set the ui.patron.default_country setting */
TR[fmfield=master_account] { display: none; }
TR[fmfield=alert_message] { display: none; }
TR[fmfield=ident_value] { z-index: -1; }
TR[stat_cat_id='1'] { border: solid thick red; font-size: x-large; }
