xterm 4.5.0 on Node.js NPM

🚀 Features

New experimental link provider API (#2530, #2710) via @jmbockhorst. This flips around how links in the terminal work by asking an addon what links are available at a particular cell when its hovered, instead of pre-parsing the entire viewport using the current link matcher API. The plan is for this to eventually replace the registerLinkMatcher API. You can test this new API by setting the _useLinkProvider parameter on the web links addon.
The alternate buffer can now be accessed via the experimental buffer API (#2713) via @JavaCS3. This breaks the previous API so if you're an early adopter be sure to update accordingly.
