Very minor documentation issue in JsonDirectoryDataSource.js

[coderintherye]

JsonDirectoryDataSource.js class comment on line 22 of current release says:

• @extends DataSource

But should say

• @extends FileDataSource

(At least as far as I can tell because FileDataSource looks to be a standalone class not extending another class)

What is this SqliteDataSource you speak of?

[coderintherye]

@NuSkooler apologies the title was incorrect but the description noted it correct, JsonDirectoryDataSource.js

@coderintherye Damn! I have that on my TODO list, was hoping someone had TODONE already!
