xhtml compliance.  style consistency, fix viewing type properties by using base type name, list all types when creating a type, tweak to not show schema screen of db when no schema support.  allow GZIP compressed DB downloads.  make sequences reset to their specified min value, NOT zero.  A few of bryan's view wizard things have crept in, but I will be working on that later.  Drop/cancel buttons instead of yes/no buttons
