Dependencies are built out of the build container and we shouldn't enforce
specific tags.
It breaks the release process (see https://github.com/weaveworks/scope/wiki/Release-Process#go-to-a-linux-host)
in machines with standard Go installations resulting in:
```
go install net: open /usr/local/go/pkg/linux_amd64/net.a: permission denied
```
* `sans-serif` breaks certain SVG viewers
* set single font: Arial (hopefully best choice)
* set absolute width and height
* remove react id attributes (saves 10%)
Fixes#1144
* Check that the protocol is TCP
* Support all HTTP methods
* Clear out tasks from table when they exit (required using task ids as table
keys). A nice side effect of this is that we can tell apart tasks receiving 0
req/second (i.e. tasks which currently aren't receiving any requests but were
receiving requests at some point) from tasks which don't exist anymore.
We report metrics fro the former.
* Simplify hash table key (no need to use a struct)
* It sends unexpected TCP RSTs (causing connection reset by peer errors in the python plugin)
