Flexible searching for administrators

This version adds a new search box to the top of the left hand side menu on all administrator pages. It allows for an efficient database search via a number of parameters:

• IPv4 address or last octet
• IPv6 address or last section
• AS Number / Macro
• Partial usernames
• Route server prefixes
• MAC addresses
• Email addresses
• Any other text is searched as %xxx% on customer details
