BUGFIX: Split audio on tier now includes edge-spanning labels
BUGFIX: Split audio on tier now includes edge-spanning labels

Before, the crop method was set to 'strict'.  This means that if
a labeled interval was not wholly included in the cropped interval,
it was not included in the cropped textgrid.

Now, the user can choose which behavior they want, but the default is
"not strict".
