Description:
Object browser is one of the features that script writers have requested for a while.

For example in tdf#66185:

> VBA features: AutoComplete, Object browser, and auto change upper/lower-case

Users should be able to see all the available objects, both in globals, and also in other libraries. This is helpful for the script writers as they can understand what is available for coding.

Please note that this is different from:

* Object catalog, available as a sidebar in BASIC IDE editor
* Developer tools, available from "Tools > Development Tools".

A similar feature is available in MS VBA editor, which shows ~1000 modules alongside their members. Categorization is very helpful.

In a LibreOffice BASIC object browser implementation, one should be able to see:

* All the available globals, categorized by <globals>
* All the other available objects, and their members

Objects should be provided as a list, and respective members as a second level list. At the bottom you should be able to see the usage. One should be able to see at least these in the list of objects:

* Modules
* Classes
* Enums

And these in the list of members:

* Property
* Sub
* Function
* Const

For example, you should be able to see "MsgBox" as a member of <globals>.

This could be helpful:
MsgBox (Prompt As String [,Buttons = MB_OK [,Title As String]]) As Integer

MSO has these libraries: "Normal, Office, stdole, VBA, Word". "MsgBox" is a member inside "Interaction" class, and is also available in "<globals>".

Search functionality is helpful, and that would a plus.
