browser.js: Adjusted condition for enabling "Commit" action; now allowed if no files are selected AND current directory is versioned (as well as if all selected files are versioned). Committing with 0 files selected will commit the current directory. ivle.fileservice_lib.action: Fixed to allow commit to contain 0 paths. This will commit the current directory instead. This fixes Launchpad bug #526161.
