Allow simple search terms on source pages

The new built-in Markdown rendering is awesome :)

In order to make it even more awesome for doing high-level code documentation, 
I'm proposing that gitiles pages that render source files also accept a new GET 
parameter `s=TERM` which will scroll the page down to the first instance of 
TERM.

A possible implementation:
  * in BlobSoyData#prettify, track for the Nth TERM. On the first hit, insert an anchor #TERM_N
  * in the javascript, if no #anchor exists in the URL and the s=TERM is present, set the anchor to #TERM when the document becomes ready.

In case it's unclear, the purpose of this would be to enable markdown files to 
link to code by e.g. function or classname, as opposed to line number. This 
should be more-impervious to drift as the code evolves.
