New Feature: persistent History to compliment snapshots

[GoogleCodeExporter]

Currently we have a feature called Snapshots which do not persist after the 
application closes. Whereas Snapshots include the response in addition to the 
request, the History we implement will only persist the request. Here are the 
features we aim to implement
* Persist request history upon application close, load request history upon 
application start
* Continue to use Snapshots for request / responses that occurs within the 
current application session; Snapshots will just be considered an enhanced type 
of History - they will live together in the same menu list, though Snapshots 
should be distinguished with a camera icon indicating their enhanced status
* Move current Snapshots menu item from under File to new top-level "History" 
menu item. This should satisfy the request in Issue 41.
* the History drop down menu should contain a separated "Clear History" item 
that will clear out the history
* The Max Snapshots user setting should be renamed "Max History"

So far we are done with all the requirements except the last two + the Camera 
icon to display next to Snapshot items in the History list.
