Make easier to create custom Vue component in plugin

[jardakotesovec]

Its already possible to create custom vue component and than add it via smarty hooks to existing UI.

But are few small improvements to make that experience easier

• Expose more basic components from ui-library to be global and therefore easily available to the custom component
• Add example to the docs to see how it can be done
  Currently if plugin create custom Vue.component, its limited to the use of global components from ui-library.

PR is now ready for review.

No objections here, @jardakotesovec; can you open a PR against one of the applications with the specially-formulated submodule update commit message, so that the Travis tests integration can run over this change?

[jardakotesovec]

@asmecher Here is the OJS PR - pkp/ojs#3977

[asmecher]

Thanks, @jardakotesovec, the Travis test didn't quite complete one run but it's nothing you broke. Are you ready for #9125 to be merged and cherry-picked forward to main?

[jardakotesovec]

@asmecher merged&cherry picked in pkp-lib. Should I always also update the the submodules across ojs/omp/ops?

[asmecher]

Please leave the submodules for now; normally it's good practice to update submodule hashes but

• our CI queue is already flooded, and
• this change is very unlikely to affect the different applications differently and
• submodule updates are likely to force other devs to need to rebase their PRS
  ...so in this case it's not warranted.

...and thanks for implementing this! I'll close the issue, unless there's something left to do here.
