update tahoe versions

update tahoe to 1.8.3, foolscap to 0.6.1, tahoe-deps to v22
Improve compatibility with ArchLinux
fall back to using curl if wget isn't found

'wget' is not included by default on OSX, but curl is.
fail gracefully if bzip2 isn't available
Add Aria support

In addition to downloading using wget and curl, the needed files can
also be downloaded if aria is on the system.
Further improve compatibility with Arch and Linux3

Add checks for ifconfig and patch with the linux3 fixes from upstream.
Fix compatibility with OSX

Verify checksums with shasum -a256
More verbose version info

When called with --version, also display what tools will be used to
dowload needed archives/patches, as well as the sha256 tool.
Update comments to show that python 2.7 is acceptable
Fix compatibility with OpenBSD/NetBSD

Add OpenBSD and NetBSD specific sha256 verifiers
Remove GNU extensions to sed

The BSDs don't have the -i parameter found in GNU sed, so we work around
it.
Add support for "fetch" on FreeBSD
Determine python and print it's info in --version
Check for tar and bzip2.

Sure, all systems should have tar but not all will have bzip2. We should
still fail earlier if neither are found.
Add info about C++ warnings

The C++ warnings are harmless so we inform the users.
Version bump to 1.2.5c
Update foolscap & tahoe deps

Update foolscap to v0.6.2
