Easy hook search

[pieroit]

At the moment plugins devs can do the following to know which hooks are available and what they do:

• read the code under cat/mad_hatter/core_plugin/hooks
• search inside the docs

Both are useful but we need a fast and easy way to know which hook is available and for what.
Ideas until now:

• simple list of hook in the docs, with link to reference
• update the discord Cat (that can be presented on website and docs) with a plugin supporting a dedicated hook search
• go for stronger autocompletion in the IDE

Additional idea, navigation from and to the flow diagram step

I will implement a simple list with reference links for now, then we will see for autocompletion...
