Added breaking test for the problem that some html-comments break can.view.Scanner (by being recognized as tags instead of comments)
Fixed a bug in can.view.Scanner that would recognize some html-comments (namely all comments, that don’t have a space/tab/newline after the starting `<!—`) as tags instead of comments and therefore try to bind them (which breaks other bindings)
Merge pull request #598 from simpleTechs/html-comments

When using certain html-comments, can.view.Scanner does not recognize them correctly
