FileNotFoundError for default dictionaries

[nsmarkop]

Similar to #1 but not quite exactly the same error message.

I get this for both palan_user and palan_sample as both fail to load in the UI.

Looking in C:\Users\nsmar\AppData\Local\Programs\Python\Python36-32\Lib\site-packages\plover_palantype, I only see the following files:

Adding my own copy of the dictionary results in stuck loading symbols / errors still for things until I remove the two failing built in ones (presumably due to the FileNotFoundErrors stopping something in the engine) -- after I remove them then the manually added dictionaries work as expected.
