Consider renaming the "support" page

[quantizor]

Generally when visiting a website, "support" as a single word is where an end-user would go to find help information. The naming is a little confusing and I think people might overlook it for its purpose: to explain and drive income for the project.

Some alternate title ideas:

• Support Webpack (basically just adding a subject so it's more obvious what the page is about)
• Contribute (my favored one - not as monetarily driven and encourages community involvement)
• Donate
• Get Involved
• Become a Backer

I agree and I think "Contribute" is best as well. I added a TODO in #1380 and will address soon with some other content re-organization.
