Non-search tags do not allow duplicate description

1) Create two campaigns in non-search tags:

Test

Test2

2) Create a source

Tag: tag1

Description: tag1

Campaign: Test

Distribution: AdDynamix

3) Attempt to add a second source:

Tag: tag2

Description: tag1

Campaign: Test2

Distribution: AdIntelligence

You get "A tag with that description already exists". It is possible to have the

same description (keyword) in multiple campaigns so adding the tag in #3 should

be allowed.

I would think the test would be that an end user should not be allowed to add

the same description if the Distribution, Account, and Campaign are all identical.

I discovered this when doing some uploads for Keith. While there is a workaround

it is painful.
