Possible Path, with backslashes, is not valid

[DanielSiepmann]

TypoScript allows usages of backslashes inside assignments (to allow configuration of classes).
The following is valid TypoScript, but can't be parsed:

config.tx_extbase {
    view {
        # Configure where to look for widget templates
        widget {
            TYPO3\CMS\Fluid\ViewHelpers\Widget\PaginateViewHelper {
                templateRootPath = EXT:ext_key/Resources/Private/Templates
            }
        }
    }
}

But we receive the following error for the line:
Tokenization error: Cannot tokenize line "TYPO3\CMS\Fluid\ViewHelpers\Widget\PaginateViewHelper {"

Thanks for the report. I'll see if I can whip up a test case for this issue.
