Fix for Bug : 1328085

Following changes are implemented.
1. Sort based on node color in "Host Name" column in node summary pages
2. Move "version","CPU","Memory" columns to the end
3. "Host name" column contents should be visible clearly with out wrapping. - Increased the column width to accomodate bigger hostnames.
4. For "Interfaces", have total and down count in seperate lines
    12 Total
    5 Down
5. Display color for all nodes in "Host Name" column.
