fix search and search pagination

# Search fix:
CRITICAL: Replaced "name=user.name" with "user_id=user.id" in fbone/templates/macros/_ misc.html, macro "render_user_table"

# Pagination fix:
1. Users per page changed from 1 to 20.
2. Removed "#" Collumn in render_user_table.
3. Created macro to paginate search results (render_pagination_search).
A lot of redundant code (render_pagination). This should be improved in the future.
