Add option to disable the stitch plan cache (#2655)

Setting the cache size to 0 bypasses the cache completely.
This is necessary during development to ensure newly-changed code actually gets run.

Also fixes the error pane in the params gui.


* make params warning pane large enough to see contents
* rename sizers in preferences dialog descriptive names
* add shapely version bound
* add option to disable stitch plan cache
* remove out-of-date wxg file
* make a cache size of 0 disable the cache
