Add installation instructions to index.html

We will remove them from the installation wiki because it is a security risk. This is somewhat inconvenient, but should be okay, and much safer.
Copy revisions

About time I spring-cleaned these texts a little.
Fix typo in example output
Add -k to curl command

Hopefully fixes #13885.

I removed the https:// and added -L so I could make the text bigger. Form over function right? Well it needs to be big so people see it. As big as possible!
Margin tweaks, but I'm no expert
Wiki link button, layout is maybe too tight
Github redirects for raw are bugged

Only seems to work half the time for http://raw.. to https://raw.. other half gives you a redirect to wiki or 404 :P
Bigger install line; Moved wiki link

Shorter install line, but this redirect works 100% now. So cool.
Change syntax of install command

Use the original `-e "$()"` syntax instead of `<()` as the latter fails when
run as root via `sudo` and produces an incomprehensible error message.

Fixes #14923.
Add enough spacing so the command is fully-visible
Fix insecure 'curl' command in install instructions

Fixes two issues:

- curl was given -k aka --insecure, which causes it to ignore SSL certificate
  errors. This makes SSL nearly useless against active tampering.

- curl was given a URL with no protocol, causing it to default to unencrypted
  HTTP.  An active attacker can filter out GitHub's HTTPS redirect or modify
  the response in arbitrary other ways.

Either of these issues makes it quite easy for an active attacker, anywhere on
the network between GitHub and the person installing Homebrew, to insert
malicious code. Since this code goes straight into the ruby interpreter, this
is a one-step compromise of the user's machine.

Since the command got longer, shrink the font so that it still fits in the page
column (at maximum width) without scrolling.

On 10.5 the curl command can fail due to missing SSL certs.  Add a note to look
at the alternate install instructions on the wiki, which now mention curl
--insecure .

Add link to Formula on marketing page

Me every time I want to know if Homebrew has a given package:
- http://lmgtfy.com/?q=homebrew+mac&l=1
- Click: "Fork me on GitHub"
- Click: "Library"
- Click: "Formula"

Now we have a one-click step to discovering what Homebrew can
install direct from the homepage. W00t!
