minor changes to database_tools (monitoring queries)
bugfix in database_tools.py

- get_stations did not return a list ordered by network, then station. Could be a problem if stations are input by hand (not ordered alphabetically in the DB)
Compute CC and Plot

* remove explicit mseed file format (thanks to Sébastien)
* add taper on each slice before calling whiten (before FFT)
* rename 07.plot_dtt.py to s07plot_dtt.py and clean content (Thanks to Kasper!)

updated travis example
dependencies, not going to work smoothly
encore...

path check
one step closer
