Issue #2384413: Fixed URL field limited to 128 characters, and not 255 which the database column supports.

Issue #2105849: Add a 'Configure' link to admin/structure/sharedblocks/publish from the modules page.

Issue #2180951: Disallow subscription blocks from being shared by adding a 'no publish' flag to hook_block_info().

Issue #1580248: Standardize delivery of block content via JSON as rendered HTML instead of render API array.

Allow new subscription blocks to be added directly from the block UI. Unified block UI forms and exportable UI forms.

Issue #2180523: Added security tokens to the published block URLs. Existing installs will have this security check disabled until manually enabled.

Issue #2181087: Fixed shared blocks should be tricked into thinking the current page is the homepage.

Issue #2181089: Added ability to apply a 'sharedblocks' text format to the shared block output. Abstracts the convert relative to absolute URL functionality to the filter system (and Pathologic module).

Now that subscribed blocks are marked as DRUPAL_CACHE_CUSTOM, sharedblocks_cron() is no longer necessary.

Issue #2180521: Fixed block rendering skips hook_block_view_alter() by adding a seperate helper function to render and process the block that mimics the code in _block_render_blocks().

Added the DRUPAL_CACHE_CUSTOM flag to sharedblocks_block_info() to indicate that we are handling the caching for these blocks.

Check expiration on block caches before using them, so that short-lived blocks don't use data that's between expiration and cron-invoked cache clear

Removed expiration and last_update fields from the DB, and fixed caching to only refresh if the cache has expired.

Make use of the CTools Export UI for managing subscribed blocks, and ripped out all the old code that handled it before
