Refresh SVN and Git repo properties

[netweb]

Switch to svn:autoprops and remove svn:eol-style properties

See ​#BuddyPress6409

Update svn:ignore, svn:global-ignore and .gitignore properties see:
​https://core.trac.wordpress.org/browser/trunk/
​https://core.trac.wordpress.org/browser/trunk/.gitignore
​https://buddypress.trac.wordpress.org/browser/trunk/
​https://buddypress.trac.wordpress.org/browser/trunk/.gitignore

Proposed to also add IDE/Editor specific ignores, e.g. .idea for PhpStorm, any others? Netbeans maybe?
(By adding a .gitignore rule to .gitignore file to allow for personal customizations (see core's implementation of this) we can proably avoid having to do this for each editor.

In 5770:

Tidy up SVN properties.

• This first steps removes svn:eol-style, svn:executable, svn:mime-type on all files.
• The svn:ignore and svn:global-ignores properties have been tidied up to match WordPress core.
• A subsequent commit will re-instate svn:mime-type via svn:auto-props.

Hat-tip DJPaul. See #2802.

In 5772:

Add .htaccess, .DS_Store, and .gitignore to .gitignore, taking influence from WordPress core.

Hat-tip netweb. See #2802.

I think adding a .idea file is fine.

If Netbeans has a directory specific configuration file, I've never needed to use that functionality myself. Most of what I do involves projects with several plugins and themes in them, all of which utilize a similar configuration.

Marking this as fixed for now, happy to revisit this later but there are a few workarounds for IDE/Editor ignore rules.

See these GitHub references:

• ​https://github.com/github/gitignore/tree/master/Global
• ​https://help.github.com/articles/ignoring-files/#create-a-global-gitignore

[netweb]

Adding some extra info in regard to PhpStorm .idea:

Per @JohnBillion in ​#WP34345

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

Assigning all closed & unassigned tickets in the 2.6 milestone to myself.
