t0060: reactivate daemon tests

ipfs object put: return error if object is empty

sharness: add function to test curl response

Config file is not executable, and must not be world accessible

sharness/README: add writing tests and debugging

Tests in this script had been deactivated because
there was no good way to wait until the daemon was
ready. Now that we can use pollEndpoint for that
it's time to reactivate the tests.

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.
