LPS-47763 Glyphicons Import

Hey Nate, here is the update for [LPS-47763](https://issues.liferay.com/browse/LPS-47763).  Just as a heads up, there are a couple console warnings that now show up - one regarding the [Compass CSS3 Shared](https://github.com/liferay/liferay-portal/blob/master/portal-web/docroot/html/css/common/_flexbox.scss#L1) module being deprecated (it offers an alternative), and this one:
```
[WARNING] MultiJson is using the default adapter (ok_json).We recommend loading a different JSON library to improve performance.
```
MultiJson is one of the new packages [referenced in the portal.properties](https://github.com/drewbrokke/liferay-portal/blob/62e3bebbf8d3c6053f3468add47ecbcadae55d6e/portal-impl/src/portal.properties#L7952) file.
