Bjoern Rabenstein b1e4956142 Apply a giant code cleanup. 
Essentially:

- Remove unused code.

- Make it 'go vet' clean. The only remaining warnings are in generated code.

- Make it 'golint' clean. The only remaining warnings are in gerenated code.

- Smoothed out same minor things.

Julius Volz c6e9f085a3 Update used Go version to 1.3. 
Go downloads moved to a different URL and require following redirects
(curl's '-L' option) now.

Go 1.3 deliberately randomizes ranges over maps, which uncovered some
bugs in our tests. These are fixed too.

Brian Brazil 4a2b96f848 Remove backoff on scrape failure. 
Having metrics with variable timestamps inconsistently
spaced when things fail will make it harder to write correct rules.

Update status page, requires some refactoring to insert a function.

Brian Brazil f525ca5d9e Let consoles get graph links from experssions. 
Rename ConsoleLinkFromExpression, as we now have consoles.

Brian Brazil 2f76f434a5 Add humanizeDuration function. 
This attempts to reasonably handle things from weekly cronjobs,
to rpcs taking ns to things that are usually ms but jump to over a second.

For consistency, stop putting spaces before prefixes.

Add a function to bypass the new auto-escaping.
Add a function to workaround go's templates only allowing passing in one argument.
