Make the issue template more robust.

This makes the issue template more robust, making check boxes so users can submit and check or check as they go.  It also starts using HTML comments so that directions for the users aren't always displayed to us (gotta love Markdown.) And provides the users with more hints on what we would like from them when filing a ticket.

-###### What version of Jekyll are you using (`jekyll -v`)?
+<!--
+  Hi! Thanks for considering to file a bug with Jekyll.  Please take the
+  the basic questions (convert `[ ]` into `[x]` to check it (or submit and check.)
+  If are no need for certain fields like output and redirection, please delete
+  those headers before submitting.  We know not all tickets require those
+  steps.  Otherwise, please try to be as detailed as possible.
+  
+  If you are unsure this is a bug in Jekyll, or this is a bug caused
+  by a plugin that isn't directly related to Jekyll, or if this is just
+  a generic usage question, please consider asking your question at
+  https://talk.jekyllrb.com where non-bug questions go.
+  
+  Thanks!
