telnet:URL scheme handling

- The inline file transfer protocols work over all transports, not just serial/modem
rz(1)on the remote host opens a file picker on the local host

SecureCRT is a follow-on to a program called CRT which originally spoke only Telnet and rlogin. CRT first shipped in 1995 for Windows 95 and Windows NT. The modem and serial communication features came in later versions of CRT. SecureCRT was a premium variant of CRT, adding support for the SSH and Telnet over SSL protocols. The two programs were offered in parallel for many years, but eventually CRT was dropped from the product line.
SecureCRT is made by Vandyke Software in Albuquerque, New Mexico.
