Order for displaying logs

[DiegoRam]

It could be better add a new parameters for RHC-TAILS: --opts '- xxx'. XXX should be an int value that define the line number returned.

Sorry, i forget tell that the order of logs must be another for our confort ;): Jboss logs firts and our application logs at end.

example:

 rhc app tail -a zentasks -p redsas --opts '-n 50'

to show 50 lines...
