Fixes http://open.silverstripe.org/ticket/6210.
Replaces the hardcoded file patterns from Folder::syncChildren() with a new static Filesystem::$sync_blacklisted_patterns to describe files and folder names to skip when running Folder::sync().
Added unit test for Folder::sync()
Extended Folder::sync() to report on the number of file / folders skipped.
The entire framework repo (with the exception of system-generated files) has been amended to respect the 120c line-length limit. This is in preparation for the enforcement of this rule with PHP_CodeSniffer.
API CHANGE: Simplified state handling so that it's just a key store. Affectors are replaced with GridField_ActionProviders. API CHANGE: Removed GridField state manipulation actions instead opting for GridField_ActionProvider actions.
API CHANGE: Removed support for modifiers that add "body" rows, instead having core support for generating the body rows hardcoded into the GridField.
API CHANGE: Allow modification of columns across the whole GridField with the GridField_ColumnProvider interface.
API CHANGE: Renamed GridField_AlterAction to GridField_Action, and added actionName/args parameters, since it can be used for all actions (including batch actions and row actions)
API CHANGE: Removed GridFieldRow class.
API CHANGE Removed File->resetFilename(), use File->updateFilesystem() to update the filesystem, and File->getRelativePath() to just update the "Filename" property without any filesystem changes (emulating the old $renamePhysicalFile method argument in resetFilename())
API CHANGE Removed File->autosetFilename(), please set the "Filename" property via File->getRelativePath()
MINOR Added unit tests to FileTest and FolderTest (some of them copied from FileTest, to test Folder behaviour separately) (from r107273)

BUGFIX Fixed Folder::findOrMake() not to create "new-folder" through File->setName() if using a trailing slash in the path (which causes an empty name). Added FolderTest to verify this. (from r101266)
