Many fixes for most operations in Eclipse.

Many fixes for most operations in Eclipse.

* Implemented global -n option
* Implemented "Questionable"
* Fixed Directory method, I _believe_ it's now correct in both cmdline and Eclipse.
* Directory method Now looks for localdir of "." and compares the repo dir, uses THIS as a basis for all directory level calculations.
* Added extra parameter to filenamesplit() to force stripping of "prepended" directory name. This ensures commits/updates etc work from any directory in the source tree.
* Modified argsfromdir() so it is "always" called. This means that when the client specifies a directory, the method can detect this and behave accordingly (this is currently only implemented for the '.' directory)
* Fixed "commit" method to correctly work from in a subdir
