Client tabs missing for Pencilblue

[jasonyueyang]

For https://github.com/pencilblue/pencilblue, client doesn't work from /glimpse/client. This could be due to the fact that pencilblue doesn't use Express.

Repro steps:

• Runnpm install @glimpse/glimpse-node --save
• Add following to pencilblue.js: var glimpse = require('@glimpse/glimpse-node'); glimpse.init();
• launch mongod
• run nodemon pencilblue
• goto localhost:8080 to use the site
• goto http://localhost:8080/glimpse/client/ to launch the Glimpse client

The request lists on the left shows up. However, content tabs are missing.

Regardless of if this is Express related, we should probably still render a better experience in these situations.
