fix(cmd): add explicit platform target
fix(installer): use deisctl-hack fork of makeself

The installer by default does a recursive `chmod` and `chown` of its
target directory, which is unwelcome in this case where we drop a single
binary into /usr/local/bin.
Merge pull request #22 from mboersma/fix-makeself-perms

fix(installer): use deisctl-hack fork of makeself
fix(README): update installer link

Also removed the install-darwin.sh and install-linux.sh scripts that
were mistakenly checked in. Instead we maintain deisctl/install.sh in
the deis.io project.
Merge pull request #23 from mboersma/deisctl-installer-links

fix(README): update installer links
fix(README): fix installer link to use http, not https

We can't provide a direct https:// download link from GitHub pages.
The installer does perform CRC and MD5 checks, but users are
encouraged to build deisctl from source.
