Implement tex2lyx -m switch (bug #8393)

Browse Source 
With this new command line switch a list of modules can be loaded
unconditionally. This seems to be needed for the literate programming formats,
and it is useful to work around bug #5702 as well.

automatically detect a given module, but you know the modules that provide
some commands or environments that are used in the imported file. The modules
are loaded in the given order. If a module \fIfoo\fR depends on a module
