Google announced they have added a new way to submit URLs to Google for crawling and consideration into Google's index.
Under the Diagnostics and Fetch As Googlebot area of Webmaster Tools, after you use the fetch feature and GoogleBot fetches it successfully, Google will allow you to click "Submit to index." Google will then consider the content on that URL and if it passes it's test, it will include the content in it's index within a day or so.
Google explains that you have a maximum limit of 50 submissions per week; when submitting URLs with all linked pages, the limit is 10 submissions per month. You can see how many submissions you have left on the Fetch as Googlebot page.
Here is how it works in Google Webmaster Tools:
Google has also crawl URL form for those who do not login and want to submit URLs to Google. That form was lost several months ago because of a bug but it returned shortly after.
