OS X Yosemite Install Instructions

[oliverdowling]

It appeared nothing was happening with issues #862 or #954, so I've added some screenshots and made a start at writing instructions for installing Bitcoin Core on Mac OS X.

I copied and pasted some from the Windows section where applicable.

I did not include how to start Bitcoin Core once installed, because there are a number of ways to run it, including but not limited to:

• Spotlight Search (Command+Space on the keyboard)
• Launchpad (there is a key on the keyboard specifically for this, but also a Dock icon)
• Finder (folder explorer /Applications/Bitcoin Core.app where ".app" is hidden by default)

My preferred method is Spotlight, however, it still displays as "Bitcoin-Qt":

Launchpad:

Launchpad with search:

Let me know if there are any other screenshots or info needed.

Staging page looks solid, I see no errors.

I noticed that my username was included in the Welcome to Bitcoin Core image, so I blurred it out.
