Remove portal-vue and vuejs-dialog as dependencies since COSMOS remov…

[mteckes]

Looks like COSMOS past 5.0.1 removed portal-vue and vuejs-dialog. Since these are gone, planetviewer cannot load because it is looking for those dependencies.

1. Remove portal-vue
2. Remove vuejs-dialog

The following commits removed these dependencies from COSMOS

remove vuuejs-dialog as external
remove portal-vue as external

I would get the following errors:

Uncaught Error: application '@cosmosc2/tool-planetviewer' died in status LOADING_SOURCE_CODE: Unable to resolve bare specifier 'portal-vue' from http://cosmos-002:2900/tools/planetviewer/js/app.js (SystemJS Error#8 https://git.io/JvFET#8)

and I also get this error:

I removed portal-vue and vuejs-dialog, built with the following commands in a virtual environment:

yarn
...
yarn build
...
rake build VERSION=5.0.5

Once built, I uploaded the GEM to COSMOS 5.0.5 in the admin tool.
