Solving a bug reported on the ROOT forum (http://root.cern.ch/phpBB3/viewtopic.php?f=3&t=16971&sid=25ac93dfe11c8ea903e260b159f49519)
Improve the spacing between lines. Due to the way the vertical text centring is done (bounding based) the
spacing between lines may appeared irregular in some cases..
Started working on integrating IgProf in PROOF
PROOF: tag identifying additional logfiles

Tags are now used for the Valgrind and IgProf wrappers, generating
additional logfiles. They are appended to the "ordinal" number both for
the master line and the workers lines. Appending tags to ordinals also
incidentally fixes a bug leading to having the additional logfile
concatenated to the ordinary logfile while getting the first.
Fixed PROOF pct of completion when getting logs
No newline in PROOF logfiles retrieval progress
Added PROOF logfiles preprocessing before sending
Added quotes for igprof cmd in PROOF-Lite
