new features in fomosto and a convenience method in mopad

Hi,

I just added two more fomosto options: One displays velocity models from config files, the other may add phases from the travel time tables to fomosto view. 
For example:

    fomosto modelview --parameters=vp,vs,qp

in a top level directory with a couple of stores produces 
![modelview](https://cloud.githubusercontent.com/assets/1038455/3749067/4f833978-17e7-11e4-8bda-7cdf8e09eae9.png).
Without --parameters only vp and vs profiles are show. 

From within a store directory phases can be added by:

     fomosto view --show-phases=begin

another option 

     --show-phases=all

would add all available phases from the TTT
