Ride editor and tools

A new tab 'Editor' for manually editing ride file data points and
associated menu options under 'Tools' for fixing spikes, gaps, GPS
errors and adjusting torque values. A revert to saved ride option
is also included to 'undo' all changes.

The ride editor supports undo/redo as well as cut and paste and
"paste special" (to append points or swap columns/overwrite
selected data series). The editor also supports search and will
automatically highlight anomalous data.

When a file is saved, the changes are recorded in a new metadata
special field called "Change History" which can be added as a
Textbox in the metadata config.

The data processors can be run manually or automatically when a
ride is opened - these are configured on the ride data tab in
the config pane.

Significant changes have been introduced in the codebase, the most
significant of which are; a RideFileCommand class for modifying
ride data has been introduced (as a member of RideFile) and the
RideItem class is now a QObject as well as QTreeWidgetItem to
enable signalling. The Ride Editor uses a RideFileTableModel that
can be re-used in other parts of the code. LTMoutliers class has been
introduced in support of anomaly detection in the editor (which
highlights anomalies with a wiggly red line).

Fixes #103.
