to_do 6.x-1.1-rc5

This release fixes a host of bugs that were in the module. These bugs were associated with the following issues:

1) #552206: wrong block links (Urgent, All) for a non clean urls site - module didn't work properly on sites without clean URLs enabled
2) #541888: error on localhost - sql bug
3) #563116: I get a similar error as Admin with no new roles defined - sql bug
4) #568040: the user can't access the to do node that assigned by others - bug in access system
5) #585842: user warning: You have an error in your SQL syntax - sql bug
6) #596254: Impossible to assign a role - sql bug
7) #572422: Unknown Table n user warning when assigning user role - sql bug
8) #674622: permission to allow or disallow users setting options for sidebar block - bug whereby users without permissions to be assigned to do list items had a pointless setting in their user control panel that allowed them to set the number of to do list items to be displayed.

As well, in this release hook_access() was rewritten, taking out the $op values of 'view', 'edit' and 'delete', and hook_node_access_records() and hook_grants() were added, bringing this module in line with the Drupal grants system, meaning that it can also properly be tied into other access modules.
