foamToC: the -allLibs option is now the default, -noLibs disables loading all libraries

the -solver option also disables the default loading of all libraries, instead
loading just the specified solver module library and dependencies.

It is generally more useful to load all the libraries when searching for model,
boundary condition etc. rather than having to list specific libraries to search
unless only the contents of the standard libraries loaded into a solver module
are to be searched, in which case the -solver option can be used.
