Update list of modules on https://cypht.org/modules.html

[marclaporte]

We have two lists of modules:

• https://github.com/jasonmunro/cypht/tree/master/modules
• https://cypht.org/modules.html

They should be in sync unless there is reason not to. Ex.: POP3 can be omitted: https://github.com/jasonmunro/cypht/issues/452
