1. Remove "Choose the group of Grants you'd want to allocate funds to:" and the two buttons "Grant Category", "Grant Collection"

2. Add title to tag dropdown, match style to Grant Creation form

So thsi means are we removing the ability to fund a collection and instead fund a particular tag / list of tags ?
