Enhancement - Option to clear existing information when searching

[GoogleCodeExporter]

What version of ComicTagger are you using?
1.12.1-beta

On what operating system (Mac, Linux, Windows)? What version?
Windows 7 x64

GUI or command line?
GUI

What steps will reproduce the problem?
1. Open a comic which already has comic information.
2. Add some additional information (eg: Format)
3. Search online for the comic's information
4. Comic information is appended to the original (eg: Format remains)

What is the expected output? What do you see instead?
I will rarely do manual editing, so I would prefer if the 'Search Online' 
always replaces any existing information. This is not always desirable though, 
so an option would be nice.

Please provide any additional information below.

To be clear, you want an option to clear the form before populating from Comic 
Vine?  Is that correct?

• Added labels: Type-Enhancement
• Removed labels: Type-Defect

That is correct. To remove any existing info and do a clean population from 
ComicVine.

To give an example of what I encountered personally- I had a number of comics 
that were populated in ComicRack several years ago. In these cases, Publisher 
was "DC Comics" and Imprint was "Vertigo." When pulling the latest information 
with your tool, Publisher was "Vertigo" and Imprint was not defined. This left 
me with both a Publisher and Imprint of "Vertigo," which is not intended.
