Improve JSDOC plugin

[fifoosid]

Feature Request Description

We need:

1. a way to hide inherited properties/methods from the docs
2. a way to know if appendedDocs have @since tag

Proposed Solution

We need to:

1. create a tag like @ignore for example, which will hide the docs for the given property/method.
2. For the second issue, we can have two approaches:
   2.1. Read the @since tag of component whose docs are nested in order to show it
   2.2 Change our concept of showing the documentation of such components(Add separate pages, rather than appending it to the "mother" component)

Instead of improving the JS Doc plugin we will integrate TS Doc in future as we are migrating all the codebase to TS.
New issue will be created.
