Qt: refactor Voip Calls Dialog into Model/View

Functional improvements:

 - "Time of day" option is now propagated to the CSV/YAML export.
 - The sorting order is preserved in the CSV/YAML export.

Other changes:

 - Convert column name identifiers to enum.
 - CSV output will now always be quoted (previously numbers like packet
   count were not quoted, but since CSV has no numeric type it should
   be OK to add quotes). Side-effect of model design decision.
 - Instead of clearing the widgets and re-adding all calls, now it will
   add new calls to the model. Not tested with a live capture, if the
   column data can change, maybe a dataChanged signal is needed.

Due to this patch, it should be easier to add a filter for finding calls
easier (e.g. by From, IP, etc.).

Note: extra QList is used in the model to ensure a O(1) lookup of calls
(rather than O(n) for GQueue).
