Detect risky answers in uplift comments

[La0]

Hello @marco-c & @calixteman,

In this PR i try to detect risky answers in uplift comments (through the optional parsing function).
As requested by Ritu, typical risky ansswers should be displayed in red (i just add another css class in the output).

Here is the Shipit issue

LGTM, but can you remove the non-ASCII characters (“) from patchanalysis.py?

This will also be useful for uplift_info, but I will take care of it in the future.

Good catch, i didn't see that one (it's a copy-pasta).
