ISSUE#5
Removed smart-table since it doesn't do what we need. Added a directive and a filter for
paging. The directive is <paged>, and the filter is "page". Together these two implement
client side paging for tables.

Right now this code introduces some redundancy. In the directive and the filter you
need to specify the page size. These page sizes must be equal. If they aren't you will
get unexpected behavior.

Updated my-tools to make use of the new directive/filter combination.
ISSUE#5
Moved a datagroups call up into the datagroups section from the other section.
ISSUE#5

the code when I corrected the issue.

ISSUE#5

the upload/download queue.
