Add title to landing page

[mikejritter]

What does this do?

• Adds 'Welcome' message to the welcome/login page.

Why are we doing this? (with JIRA link)
Jira: https://collectionspace.atlassian.net/browse/DRYD-1306

This adds additional information to the page title about the purpose of the page. I was stuck between deciding on Welcome and Log in (similar to the ServiceLoginPage), and ultimately settled on Weclome. Updating the message isn't a problem if it needs to be changed.

One odd thing is that the description for both the LoginPage and the ServiceLoginPlage have the same description. It might be worthwhile to simply rename to the LoginPage since it now directs the user to the login form.

How should this be tested? Do these changes have associated tests?

• Run the devserver
• Navigate to localhost:8080
  • Note: You might be automatically redirected to the service login page, in which case you can login and logout to get back to the welcome message
• See that the title of the page includes Welcome

Dependencies for merging? Releasing to production?
None

Has the application documentation been updated for these changes?

@mikejritter I think you're right about renaming LoginPage. How about making it WelcomePage, since that's what it really is now?

[ray-lee]

@mikejritter We could have WelcomePage be at /welcome, change / to redirect to /welome, and change /login to redirect to the services login page.

[mikejritter]

@ray-lee Changes are now made for renaming LoginPage to WelcomePage and updating the route for the page to /welcome. Master ended up being merged twice and the displayed changes were out of sync, so I rebased and did a force push to clean up the PR.

I was having some trouble testing that the initial request on / will redirect to /welcome as I automatically get redirected to cspace-services/login. I'm not sure if that's a webpack thing or what because I noticed core.dev doesn't have that behavior.

This looks fine. Never mind about redirecting / to /welcome. I forgot that / is set to redirect to /search, which requires auth, so it bounces you to the services login page. That can stay the same.
