Allow multiple upload fields and add logo option to labels

[smb]

Changed handling by id to look for a "uploadFile" css class.

Needs npm run dev/prod call for final deployment to master (but i think it's also needed for other changes in dev)

Hi - thanks for this! What problem does this solve?

[smb]

Allow preview + size check for multiple "logo" files in branding settings (currently only site logo does this):

also the next step (already working on this) is to move this code to a template/partial and add another one ("label logo") to be printed on asset labels.

[smb]

should i create another PR with the "logo on label" coding or just commit here and rename the PR? (since the new one would be build on commits of this one it would make sense to merge them into one PR)

You can just add to this one, and let me know when it’s ready - thanks!!

Feel free to test!

Custom CSS added: (to demo new css options in label printing)

  .label-model::before {
    content: none;
  }
  .label-company::before {
    content: none;
  }
  .label-asset_tag::before {
    content: none;
  }
  .label-serial::before {
    content: "Serial: ";
  }
  .label-name::before {
    content: none;
  }  
  label-qr_text {
    font-size: 0.2in;
 }

Result:
