Capitalised the DOCTYPE to meet standard syntax and fix highlighting err...

Simple but important for a template. Easy fix. Apologies if I've done the pull request incorrectly, this is my first one on GitHub. Have a nice day.

See #1522, #1112, #1059 and #335.

Okay, do as you please but I will say that the uppercase doctype was required by xhtml and the lowercase version hightlights in red in many text-editors. I see no reason not to change it other than wanting the entire document to be lowercase which it isn't anyway.

There's a lot of discussion in those previous issues. It's worth reading through, especially since the change back to lowercase was just last month.

[Arcovion]

All the other tags and attributes are lowercase though, personally I like it much more.
It sounds more like a problem with your editor than anything else, but it's true that it still tends to be that way and used to be the standard; Haml, Slim and Jade all return uppercase.

I don't think we can say much that hasn't been said already, it's NEVER mattered either way. One is a tradition, the other is consistent with all the other tags - unless you want to use uppercase for everything :P

@brianmillar9 can you be more specific? Thanks.

some IDEs and HTML Editors

@brianmillar9 thanks for the pull request, but will be sticking with lowercase. The highlighting problem represents a bug in the IDE/text editor, and thus, it should be fixed by them (if they haven't already)
