Add charm meson SL decays, Lc -> Lmd eta pi and tune cuts for charmed baryon SL decays

This request intend to add SL decays of charmed hadrons (e.g. D and Ds) from beauty. We have tested their rates and you can find them in the following.

The number of input events is 10000.

We have added some lines with tighter cuts than previous ones so as to avoid prescaling. A new line corresponding to \Lambda_c^+\to\Lambda\eta\pi^+ is also added.
