Allow user to set own text per profile

Adds ability for user to set arbitrary text to be used instead of domain matched URL.

Useful when multiple sites share account data:

example: ebay.co.uk and ebay.com share account information. Can now create a single profile using "ebay.co.uk" to generate the hash, and still automatically pick the correct profile based on URL.
