esprit update, missing subdomain facility, File Manager enhancements

Sorry about the last commit, which conveniently left the subdomain changes out 😉

Changelog from Sunday’s work, which includes a couple of enhancements and miscellaneous fixes:

• Added: octal permission view to File Manager
• Fixed: ownership of parent directory following extraction leaves root:root ownership (bug #67)
• Fixed: file permission change results in “Invalid Directory” message
• Fixed: MySQL Manager, PostgreSQL Manager, phpMyAdmin, and phpPgAdmin password field types converted from text to password
• Fixed: return value on SQL_Module::edit_mysql_user() always returned false
• Changed: Increased Urchin profile allowance to 2 free profiles per account
