add a /slaves status page that only shows slave status (comes with patch)

[jhford]

I have 130 slaves that each have tons of builders associated with them. These slaves are also very commonly offline (they are phones) which means that nearly every time I load /buildslaves it is only to see if the slave is building, idle or disconnected. This patch is to create a new page /slaves that only lists the slave, admin, last heard from time and status. While /buildslaves does give me this information as well, it is slow to generate for me and requires a full screen of text for one slave which makes the information very difficult to work with.

I have sample output from my (0.7.12) master at  http://pastebin.mozilla.org/708252 . That is one slave's builder list.

this patch replaces the other two already attached.

sorry about the multiple patches. The first two patches attached to this bug can be fully ignored. It turns out that git diff is a little different to what i am used to doing (hg diff).

As discussed in IRC, this should really be a URL parameter for the regular /buildslaves view, maybe /buildslaves?no_builders=1

Make the buildslaves display optional in the /slaves display
