customFullTimeFormat: add optional detail argument, use it in query overview

1. I added a second argument called 'detail' to customFullTimeFormat. If
   present and false, the string returned will be truncated to two time
   units -- e.g., hours and minutes, or minutes and seconds. If missing
   or true, the full detail string will be returned.

2. I added µs as one of the units of time. It's weird to have hours,
   minutes, seconds, ms, then skip straight to ns.

3. I made 'H' lowercase to match the other time unit cases.

4. I set the 'detail' argument to 'false' on the query overview tab.
   Everyone else, it's still full detail (albeit with µs).

myria-web: report concise runtimes where appropriate

E.g., in infoboxes about operators, in the network view, etc.

The only place we need detailed times is in the gantt charts and x-axes.
networkvis.js: UI fixes for sender

1. The average number of tuples can be different on the source and
   destination sides, when different numbers of nodes are involved. We
   were using the destination average as the source average. Fixes the
   second half of #135.

2. The average line was a little bit short on the source side, because
   its height was set by the matrix width not the matrix height. Fix this.
