RFR: 8256048: Incomplete gitignore setting for netbeans project

[Jie Fu]

Hi all,

The gitignore setting for netbeans project seems to be incomplete.
Only nbproject/private/ [1] is ignored. 

But there are also other files under nbproject/, which should be ignored too.
----------------------------
$ tree -L 1 nbproject/
nbproject/
├── configurations.xml
├── private
└── project.xml
----------------------------

It would be better to fix it.

Thanks.
Best regards,
Jie
