Rather than a flat list of topics to watch for, it is an indexed list
of topics to watch for in those specific positions. As such, items in
that list may also be zero (null, matches any topic), or a list of
topics (matches any one of those topics).

Additionally, topics are always specified using 32 bytes, so there is
no need to specify length explicitly.

Poke with [%watch %sometag config:eth-watcher] to initialize,
then subscribe at /sometag to receive updates in the shape of
[%snap snapshot:eth-watcher] for initial and on-reorg logs,
[%logs loglist] for logs as they happen.

…coding. (#1068)

Added support to `lens-command` for outputting a pill. We want this so that we can create (solid and brass) pills from `urb.py`.

This also adds an optimized base64 encoding routine. The previous version of base64 stack overflowed on large inputs, and a tail-recursive version took hours to encode 5mb of data. This one uses the `ripn` jet and only takes a second or two.
