refresh macaulay2 interface a little bit

[fchapoton]

• changing the official link to macaulay2.com
• gather some optional annotations
• a few pep8 details fixed

📝 Checklist

• The title is concise, informative, and self-explanatory.

Looks okay to me and does some good cleanup. Before and after this branch I get the same doctest failures. This is on OS X with the homebrew installation of Macaulay2. For example with this branch:

% ./sage -t --optional=sage,macaulay2 src/sage/interfaces/macaulay2.py
too many failed tests, not using stored timings

Is there a ticket to fix these?

[jhpalmieri]

I don't know how to fix the problems with _sage_, but the others seem not so hard. For example, the version problem:

diff --git a/src/sage/interfaces/macaulay2.py b/src/sage/interfaces/macaulay2.py

I have fixed some of them. Now doctests pass for me with macaualay2 1.19.1 from ubuntu

[fchapoton]

I have also used your suggestion for a better version method.

[fchapoton]

The other failures seem to depend on M2 version in use. Yours is the latest 1.22 maybe ?

[dimpase]

looks good

Yes, 1.22.

Thank you for the fixes!
