breaks "Angular Language Service"

[mikaeljensen]

With both "IntelliSense for CSS class names" and "Angular Language Service" enabled, following happened.

Starting VS Code in a pretty basic test project spawns a VSC process that continues to increase memory consumption at 10-13% CPU load (i7-6800K) ultimately resulting in ALS repoting "JavaScript heap out of memory".

Closing VS Code does not kill the process, but leaves it running at CPU load and memory fluctuating around 2-3 GB.

Disabling Angular Language Service makes everything else work.
Disabling IntelliSense for CSS class names makes everything else work.

When adding IntelliSense for CSS class names, the output for ALS shows

Note that, there is an similar issue breaking the Polymer/vscode-plugin, so the "fault" is probably in here.

I guess this issue has been fixed in the latest update. Thanks to Erich Gamma for this great pull request #90.
