Make Quick Fix "Add tag library definition" work with KB Model instead of using plain tag library list

WTP Validator marks unknown tags with problem markers: "Unknown tag (<prefix name>:<tag name>)"
We should take all tag libraries in the project which contain the same tag name and offer quick fix "Add tag library definition" for all of them.
Tag libraries with default prefix the same as "prefix name" from problem marker should go first.

Test case:

EXECUTE:
1. Create JSF Kick Start project
2. Open hello.jsp file in Visual Page Editor
3. Add tag <x:if></x:if>
ASSERT: New tag is marked with problem annotation "Unknown tag (x:if)"
EXECUTE:
4. Point mouse to tag <x:if>
ASSERT: Should be 6 quick fixes in Text Hoover:
