[NEW PORT] PyCharm Professional

[Guido Kollerie]

Hi,

Would someone please commit this new port to the ports tree?

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=242705

Short recap:
 - it's based on the existing port devel/pycharm-e
 - it's marked RESTRICTED as its license does not allow redistribution
(still waiting for an approval from Jetbrains)
 - I've been using the port successfully for the past half year.
 - files/pkg-message.in documents things to be aware of

Cheers, Guido
