Document PHPStorm .idea ignore in .gitignore and svn:ignore

[netweb]

PhpStorm uses an .idea folder in the root folder to store project configuration etc.

Ignoring this folder in .gitignore is helpful for people using the PhpStorm IDE.

This change actually snuck in under the radar via r35242.

I see no real problems in keeping this, though it should be moved toward the bottom of the .gitignore file and also added to the svn:ignore properties for VCS configuration parity.

woops that's my fault! I should have mentioned something accompanying the patch I submitted. Sorry 'bout that.

document .idea addition to .gitignore and relocate to end of file.

IDE-specific .gitignore rules should not be present in a project. They should be managed in the user's ~/.gitignore_global.

I documented and relocated in the .gitignore file. However, I don't do WP contributions via svn (just doing git right now) and really don't want to checkout the svn repo so if someone could take care of the svn:ignore that would rock.

In 35254:

Remove an IDE-specific rule in .gitignore. These should be managed in the user's ~/.gitignore_global file.

Fixes #34345

#facepalm of course!

Thanks John, hadn't thought about that's really where these ignores should be made :)
