[WIP] Desktop App Download Page

[wbobeirne]

Prerequisite to #557

Description

Adds a download page at /download that describes the app, and links to downloads for it. Most of the text here is just placeholder to give a sense for layout.

Changes

• Adds a new route at /download that renders the DownloadPage component.
• Adds a prop to TabSection hideHeader that makes it not render the header.

TODOs

• Figure out if we're still going to offer the HTML version
• Provide screenshots for all platforms
• Finalize copy / what we say about it
• Fetch version number / direct download link from Github release

Overall it looks good, there are a few things I'd like to see changed though.

• The blue gradient seems to have a weird transition effect whenever I render the page
• Not sure if this is intentional or not, but if we're not going to show the nav, we should be putting this page on a seperate subdomain like download.mycrypto.com
• the 'work offline' icon should be updated to something more like this to represent an 'offline' status instead of 'online'
  • 
• Are we initially releasing this for OSX only? If not, we should provide users the option to download other platforms. Hyper has a good example of this

• The gradient transition was intentional, but by no means has to stay. Just trying things out.
• I also considered a separate domain, since I felt that this page really didn't "fit" in our template. It would be easy to port to a separate project.
• Agreed, I didn't put too much thought into these info blocks, they were mostly FPO.
• That text is dynamic. I'll need to get screenshots for all OS's, but it's detected from the browser info: https://github.com/MyCryptoHQ/MyCrypto/pull/1149/files#diff-b0b9d12848a680b1032597632b7c90b4R50
