Examples menu lacking "category"

[ubidefeo]

[update based on @kittaakos 's comment regarding other submenu lists lacking category]
Akos has noticed that for

• Tools > port we miss the Serial ports and Network ports category
• Sketch > Include Library we miss Arduino libraries, Contributed libraries and Recommended libraries
  these are also to be added in the same style

Describe the bug
When opening the Examples submenu, the examples are listed with separating lines, these are supposed to have a category string

• Built-in Examples
• Examples for any board
• Examples for {CURRENTLY SELECTED BOARD}
• Examples from Custom Libraries

To Reproduce
Steps to reproduce the behavior:

1. Go to File > Examples

Expected behavior
These "labels" should be introduced.
The last one should read (mind the case) "Examples from user libraries"
The Java IDE has this division

Also worth notuing that the Examples menu fails to scan the libraries for examples, as the IDE 1.8.x does. See @ubidefeo 's screenshots to see it.

Thank you for reporting it, @tigoe. I think it is off-topic.

I opened a follow-up issue with your remark: https://github.com/arduino/arduino-pro-ide/issues/442. Please comment there and help us figure out what problem did you find. Thanks!
