New function - ec_file_presave() - adds or removes a file product to the database
Adding and removing sellable files now works properly.

own function - ec_file_node_load()

Added an additional confirmation question when requesting to delete a single node when that node
has file products attached to it, and those files have been purchased by a customer.

we need it in a new function - ec_file_preprocess_page() - which provides
a theme variable to page.tpl.php - ec_file_purchased_files - which is the
number of files a user has purchased.

of situations, e.g. if there were issues with the availability of the
payment gateway.

* Renaming theme_ec_file_node_form() to theme_ec_file_upload_form()
* Making sure the function properly emulates theme_upload_form_current()
* Fixing the logic in _ec_file_form_submit() to work in 2 separate file upload cases:
  1. When a file is uploaded before the form is submitted, by clicking the Upload button.
  2. When a file is uploaded on form submission.

Brought the module into line with drupal coding standards, thanks to coder.module

Fixed up the sql query for returning all file downloads for a user.
Commented out all mentions of file expiry, as we're not supporting this functionality right now.

Changed permission from 'hide upload info checkboxes' to 'show upload info checkboxes'
Added a user/myfiles menu item which redirects the user to their purchased files, at user/%user/store/myfiles
Some small whitespace fixes.
Cleaned up ec_file_file_download() which works as follows:
* If file is sellable and the user owns the node which is being viewed, grant access.
* If user has bought the file, grant access.

Added more descriptive info about how the checkboxes work to the README.

through a transaction workflow, and has added ec_receipt_return_page() to create the
return url for when an order has been completed.

Added a user/myfiles menu item which redirects the user to their purchased files, at user/%user/store/myfiles
Some small whitespace fixes.
Added ec_file_ec_receipt_post_save() but will remove next commit, because gordon has a better way of taking users through a transaction workflow.

ec_file_display_purchased_files_as_block() should be
ec_file_myfiles_link_list and not theme_ec_file_myfiles_link_list.

Some minor code formatting.

    This has meant:
    - Renaming ec_file_my_overview() to ec_file_display_purchased_files_as_table(),
      which displays a user's purchased files as a table list.
    - Creating a similar function, ec_file_display_purchased_files_as_block(), which
      displays a user's purchased files in a block.
    - Adding ec_file_block() to provide a 'Purchased files' block
    - Added a new theme function, ec_file_myfiles_block()
    - ec_file_my_overview() is now ec_file_purchased_files(), which returns all files
      purchased by a user, as an array.
    - Moved a whole stack of code out of theme_ec_file_myfiles() into its own function:
      ec_file_format_file(), which takes a file array as an argument, and returns
      an array of the following elements:
      File title, file size, expiry date, link to download file
    - Added theme_ec_file_myfiles_link_list() which themes all purchased files as an
      html list of links, one per line.

    Minor code cleanup.
