v2.6.14

This is a small release that fixes a couple bugs and adds a quality of life features.

Features:

• The link command now takes a new argument --use-host-header which will use the HTTP host header to generate the callback ip when using templated downloads

Bug Fixes:

• When the client loses server connection, it will now close any remote forwards it had open, otherwise reopening your remote forwards is impossible.
• Fix an issue where the ip address given from forwarding the server port would be unparsable, stopping connections from working properly when pivoting.
