Sample links at documentation are wrong

[Sairony]

Scroll down to the bottom of https://www.boost.org/doc/libs/1_69_0/libs/gil/doc/html/index.html to the samples. Clicking any of the links downloads the file instead of opening it up in the browser ( at least on chrome ). Probably this is due to the file extension being .cpp, when in actuality it's a html document.

@mloskot Wasn't sure if this should have been a separate issue,
In the GIL design guide , in the concepts page , the definition of concept equality_comparable seems to have a small typo it should have the signatures
bool operator==(T x, U y);
bool operator!=(T x, U y) { return !(x==y); }
instead of
bool operator==(T x, T y);
bool operator!=(T x, T y) { return !(x==y); }
as from the ConceptsC++ Concept Web.

@codejaeger Good catch, if you're willing to submit PR, it would be helpful.
