Added calculations and new functions for so-called IC and TC values to the RAxML support and consensus tree functions.
IC and TC values were proposed in Salichos and Rokas 2013:
Inferring ancient divergences requires genes with strong phylogenetic signals. Nature 497: 327-331.

There are several new options:

the -f i function is analogous to the -f b function with the only difference that it annotates the branches/splits/bipartitions of the reference tree passed via -t
with IC values rather than bootstrap support values.

the new -L MR|MRE|T_<NUM> function is analogous to the stand-alon consensus tree building function, but will also
annotate the branches/splits/bipartitions of the calculated consensus trees by IC values rather then support values.

Both options will also print out the respective TC values (sum over all IC values) as well as a relative TC value that is normalized
by the number of bipartitions in a fully resolved unrooted tree with n taxa.

Note that, this is still an experimental version and still needs to be thoroughly tested.
