Did a bunch more stuff

I changed to getopts long, also now you can download just a subreddit.
Tried getting the write to file stuff cinched up.
Added $url definedness check, forget why
Wow even more stuff

Added mongodb support...kinda
I didn't really read very much about it and more or less slammed our data in there willy nilly.
I needed to remove all periods from my hash keys unfortunately...replaced with semicolons. We could really use a better data structure there.
Considering just dumping it in flat files/JSON...or sqlite...anyways it's a recursive data structure that looks kinda like this
Whatever, I just let it happen.

$output = {
	$now => {
		url => {
			reddit.com/.rss => {
				url => [ top story 1, top story 2 ... ],
				title => [ top story title 1, top story title 2 ],
				url_comment => [
					{
						top_story_1_url => [@comments]
					},
					{
						top_story_2_url => [@comments]
					}
				]
			}
		}
	}
