Added identifier for package nodes

[Rishav159]

The nodes that includes packages will now have '(P)' appended in their filename.

@Rishav159 Thanks! @jdaguil your to review

@Rishav159 could there be another way may be with an icon for the node rather than adding extra characters to the node name?

[Rishav159]

@pombredanne I should not mess with the color of the circles present in the node as it represents the status. Maybe I append some icon in front of the node? Will that be fine ?

@jdaguil what do you think?

[Rishav159]

@pombredanne @jdaguil I changed the color of the text-background to green instead of appending '(P)' in the filenames, to identify if the files contain package information.
Please review.

Hi @Rishav159 I'll review this soon. For any pull requests, we would want to merge them into the develop branch and not master.

@jdaguil Okay. I will make the PR again to the develop branch.
