Enable usage of categorized repositories

This change allows to categorize repositories in component selection
page. Using categorized repositories will by default show only
uncagetorized repository items in tree. Selecting one or several categories
using checkbox will update the treeview to show all selected categorized repository
content. Repository's metadata is fetched only after the category is selected.
Categorized repositories can be defined in config.xml:
<RepositoryCategories>
    <RemoteRepositories>
    <Displayname>category 1</Displayname>
    <Repository> <Url>(url)</Url></Repository>
    </RemoteReposiories>
    ...
<RepositoryCategories
