Regex fails to parse remote connection string when username contains underscore

[scotthovestadt]

This RegEx needs to be updated to include an underscore:

^([a-zA-Z0-9\-\.]+)(\:.*)?@([^:]+)(\:.*)?$

For example:

^([a-zA-Z0-9\-_\.]+)(\:.*)?@([^:]+)(\:.*)?$

This is then correctly parsed: username_underscore@host.com:path/
