Added the ability to disable SHA-1

Improvements

• Added the ability to disable SHA-1 algorithm for SSH server with SSHSERVER SHA1 OFF command.
• Added the ability to disable SHA-1 algorithm for Webserver with WEBSERVER SHA1 OFF command.

Additional Notes:

• From firmware 2.8001.00041 and up, the following has changed:
• This firmware enabled IPv6 support for the 4-Series Control Systems. IPv4 networking is still supported with this release.
• IPv6 can be configured from the command line, as well as through the WebUI.
• To use any IPv6 socket communication from SIMPL+ or SIMPL#, your program needs to be compiled with an updated database:
• Device Database 200.245.001.00
• Crestron Database 216.05.002.00
• Include4.dat 2.19.036
• Please see the IP Guidelines for the IT Professional document (Doc. 4579N) and OLH Article 1001836 for additional information on IPv6 networking.
• SNMP cannot be enabled/disabled anymore through ENABLEFEATURE but should be enabled/disabled with SNMP ON/OFF console command.
• When downgrading from 2.8001. firmware to 2.7000. firmware, any SNMP settings that were made while on 2.8001.* firmware will be removed.
