Add a refresh button (or similar) to the Optional Dependencies dialog in the 'help' menu

Now that the conda package manager plugin (CPMP) is "running" the optional dependencies dialog should be able to update on opening, or if not possible, at least add the ability to refresh it in case you actually installed the dependencies using the CPMP

What steps will reproduce the problem?

1. Click the dependencies item in the help menu

What is the expected output? What do you see instead?

I would expect to see an updated version and not just a fixed version calculated on spyder startup.

Mmmh, what if a module is updated while spyder is running ? Spyder uses the old version while the new version would show up.
Also I think that spyder does lots of checks at startup, for pylint for example. A user seeing pylint in the dependencies but having the corresponding widget not working would have a hard time to understand what's going on.
Maybe add a label like "Please restart sypder to update the dependency list".

Having dynamic loading of all optional modules would be great, but it would require to update the core of spyder. Maybe for a version 3 ?

Sure, that is a possibility, but that could be somehow checked...

Then again why would a module under normal conditions update by itself when running spyder... I knoq it can happen but the idea is to use the package manager for those things, no?

I really like the idea of having dynamic loading of many things in spyder, I mean if at somepoint we keep adding features and just assume that at startup everything is perfectly setup for an user, we might have a long waiting time, maybe it would be nice to startup with a minimum load and leave the rest for when spyder is already loaded?

With the restart PR now we can offer this restart button/dialog here.

Also for the dynamic loading of modules, you had in mind something like this?

reload() can have many side-effects, I don't know if it would be reliable enough for plugins. I think I was more thinking at how IEP manages plugins, you can load an unload them dynamically without restarting the UI. I Have no idea how it works behind the scenes.
