Provide a simpler view for the reference path

[BitOne]

For now, reference path is displayed using a cumbersome format. For example:

--------------------+
| Id: 0x7f94a1877068 |
| Type: object       |
| Class: MyClassA    |
| Object Handle: 4   |
| Size: 72 B         |
| Is root: No        |
| Children count: 1  |
+--------------------+
         ^
         |
         3
         |
         |
+---------------------+
| Id: 0x7f94a185cb60  |
| Type: array         |
| Size: 72 B          |
| Is root: No         |
| Children count: 100 |
+---------------------+
         ^
         |
    second level
         |
         |
+--------------------+
| Id: 0x7f94a185ca20 |
| Type: array        |
| Size: 72 B         |
| Is root: No        |
| Children count: 1  |
+--------------------+
         ^
         |
    first level
         |
         |
+---------------------------+
| Id: 0x7f94a1856260        |
| Type: array               |
| Size: 72 B                |
| Is root: Yes              |
| Execution Frame: <GLOBAL> |
| Symbol Name: myRootArray  |
| Children count: 1         |
+---------------------------+

This could be reduced to: $myRootArray['first level']['second level'][3]
