The heuristic used by the default version comparison is simple. A
version string is scanned for strings of digits, split into an array of
these strings, and then an element-wise comparison is done.
This fails when presented with something like
Version.new("1.0.0beta7") <=> Version.new("1.0.0")
because the first three digits match, and the fourth digit of the
receiver (7) is greater than the assumed fourth digit of the parameter
(0).
Fix this by defining an element-wise comparator on a new VersionElement
class. This allows us to correctly compare "alpha", "beta", and "rc"
style version strings, and keeps the logic out of the main version
comparison.

This will allow us to do comparisons like
if MacOS.version >= :lion
and hopefully deprecate the MacOS.<name>? family of methods, which are
counterinitutive.
the ghc formula had an explicit version because we had trouble parsing
the version from the 64-bit URL. It is working now, so add a test to
ensure it isn't broken in the future.

Commit 2695821e98 ("Only use the bottle if its version is up-to-date")
essentially broke the ImageMagick bottle, because the version parsing
logic returns "1" as the bottle version.
Fixing this requires only a slight modification to the bottle URL regex;
includes a test.

SourceForge links can end with /download which appears to be part of
what is used to drive mirror selection. Modifying the version detection
extension of pathname.rb to detect this case for both sourceforge.net
and sf.net download selections.
This is sufficient for version detection but may not be sufficient for
other uses of /download links. I have not found any problems with links
that use /download, though.

Sphinx currently has a download name 'http://sphinxsearch.com/downloads/sphinx-1.10-beta.tar.gz', which homebrew currently can't correctly identify - with a small change to the regex for 'foobar-4.5.0-beta1' (make that trailing number optional) - it works like a charm.

* Break single test case class into several test cases.
* Fix broken arch test.
* Make update tests optional (seem to only work for mxcl).
* Add more tests.
* Move fixtures to separate folder.
