Added link to funds in preparation for fund pages.
Removed submodules.
Added submodules back in, but this time in a subdirectory.
Refactored financial statements.

1) Removed size field.
2) Parse financial statement to get date so user doesn't have to specify it.
3) Upload financial statements inline, instead of via a separate modal.
4) Allow multiple file upload.
5) Removed editing of financial statements -- just remove and add.

The result is a much simpler and more convenient uploading process.

Also removed description from fund. That will be handled in a separate
table later.
