Update version number
Fix typo in dependency
Add mnemonic constants:

kHAlignLeft=10, kHAlignCenter=20, kHAlignRight=30,
kVAlignBottom=1, kVAlignCenter=2, kVAlignTop=3

They allow to write: object->SetTextAlign(kHAlignLeft+kVAlignTop)
provide symbolic values for different styles as suggested here:

The option "A" in the `Draw()` was not cleaning properly the current pad.
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
PROOF GUI support for log filtering via pipe cmd
Some debug in PROOF log retrieval
PROOF: automatic igprof-analyse for IgProf pp logs
No bloating IgProf output and clearer profile type

Now the tag to invoke IgProf performance profiling is "igprof-pp" and
no longer "igprof" alone. Leaves some space for adding IgProf memory
profiling.
