Excalibur console message should automatically update for release

[jedeen]

Excalibur 0.11.0 does not show the correct label in the browser console (0.10.0 does, but this was prior to our automatic version proliferation).

Steps to Reproduce

npm install excalibur@0.11.0

then

var game = new ex.Engine({
    width: 800,
    height: 600
});
game.start();

Check the "Powered by Excalibur.js" text in the browser console.

Expected Result

"Powered by Excalibur.js (v0.11.0)"

Actual Result

Environment

• browsers and versions: Google Chrome 58.0.3029.110 (64-bit), Mozilla Firefox 53.0.3 (32-bit), Microsoft Edge 40.15063.0.0
• operating system: Windows 10 Pro
• Excalibur versions: 0.11.0

Thinking about this--this gets substituted at build time, the core repo gets built, then it commit+pushes to the dist repo. I believe the way to handle this through the automation in #777 is to ensure we substitute the right version before we scaffold a release/tag in the dist repo. We can detect that we are building a tag in Travis.

To fix it currently, @eonarheim could patch the tag and re-publish over 0.11 or issue a patch release tag (0.11.1).

Should be done by #867
