Install casks into HOMEBREW_PREFIX/"Caskroom" instead of the Cellar.
This prevents us from colliding with normal Homebrew Formulae.
NOTE: this will be a breaking change, with the following effects:
- all installed casks will no longer be reported as installed
- orphans all existing casks in the Cellar
- no automated facility for cleanup or migration of existing casks
refs #38, where we can discuss the implications of this before cutting a
new release
Options can be passed on the command-line and/or using
the HOMEBREW_CASK_OPTS environment variable (which has
lowest priority). There is a single --appdir=PATH option
right now, but this commit enables future awesomeness!
Other minor changes:
* `brew cask help` now returns the same thing as `brew cask`
instead of saying there was “no such command as help”.
* The HEREDOC block now uses Homebrew's #undent instead of the
customed-rolled #gsub version. Cleaner and more flexible.
* `Cask.set_appdir` has been renamed to `Cask.appdir=`. This
is more Rubyish, and of little consequence (the only place
it was previously used was in the tests).
`md5`, `sha1`, `sha256` all take a hexdigest string, e.g:
sha1 'f645e9da45a621415a07a7492c45923b1a1fd4d4'
`no_checksum` takes no argument, and indicates there is no checksum
for this cask. This is *not recommended*, and should only be used for
casks that have no versioned downloads.
`brew cask install` will complain if there is no sum provided (unless
`no_checksum` has been invoked), or if the sums do not match. It will
provide the computed checksum so the cask can be easily amended.

should take care of #104
this was a subtle one - after i reorganized the requires, plist/parser
was getting double required, which broke plist parsing and hence dmg
installs
homebrew does internal caching in ARGV that prevents us from doing the
`ARGV.clear; ARGV << 'newarg'` trick twice.
rather than try to further reach in to homebrew's innards, i figure it's
better to just pass multiple arguments down to homebrew code at once,
since it already supports that
refs #47
this delegates to homebrew's uninstall to get its work done. vanilla
`brew uninstall` actually works, but this gives us a more consistent
interface.
as discussed in #47
should address #33
includes cleanup and tests
i'm not crazy about leaning on installing/uninstalling caffeine in the
tests. it makes for some unnecessarily heavy tests and downloads. but
i'd rather get tests in place first then fix the warts.
I chose Caffeine since it's relatively small to download. Eventually I'd
like to switch this up so we bundle a dmg, zip, etc that the test suite
wires in to verify that we do the Right Thing (tm) with all those file
types. Probably will want to support `file://` URLs in Casks to help us
for that use case.
