Use XML highlighting for .xaml files

[le717]

For #8331. Also alphabetized array.

[peterflynn]

@le717 I'm not sure if alphabetized is necessarily the right order. Semantic grouping might make more sense, e.g. placing .atom & .rss next to each other. Or at the least, the "core" .xml extension should probably we listed first instead of last...

[le717]

So what about a more semantic array look like? Perhaps I should just revert the sorting and add the one extension to the end (beginning?) of the array unless the other arrays in the file are already semantically ordered.

[peterflynn]

Some of the other long file extension lists are roughly clustered semantically. I think it's fine to keep the old sort order and put .xaml at the end (though maybe move .xml to the beginning?).

[le717]

@peterflynn Done. Sorry about messing up the sort order. :\

[peterflynn]

@le717 No worries -- never hurts to explore cleanup ideas!

I think the ".xaml" entry shouldn't have a leading "." though -- but after that this should be good to merge.

[le717]

Apparently I can't get even a starter bug right...

Change will go up in a few minutes. If you want, I'll rebase and remove these bad commits.

[le717]

@peterflynn Rebased, ready to go.

[peterflynn]

Perfect! Thanks for the rebase, too. Merging...

Wow, thanks!
