t0110: replace wget with curl

Ipns/trickle append

respect contexts in a more timely manner

`gc` is actually `repo gc`, reflect in docs

commands.NewRequest() has unexported type in it's arguments

Move the comment back to where it belongs

not exactly elegant, but fixes #871 in the short term. in the mid term, unless more `repo` commands show up, i suggest just replacing `repo gc` simply by `gc`.

This removes the dependency on wget, and, while at it, cleanups a bit.
