MAINT: Move files from top level into qgrid/ directory.
MAINT: Remove global remote_mode option in favor of per-grid setting.
Two small fixes.  First is in qgrid.py, self.remote_mode was a reference to the previous name of this variable.  Second, in __init__.py I just added a kwarg to show_grid so that remote mode could be specified in that call.
