crash in getALLdata

[sousasag]

Got the following error when trying the example code:
In [16]: user.getALLdata("CoRoT-7", downloadPath=mypath)
It downloads all the FEROS and HARPS spectra, but then fails to ESPRESSO which I guess don't have any observation.

It would be nice to:
1- add an option to select the instrument and eventually configuration to select files to download
2- separate in folders for each instrument when downloading all data

Latest commit solves point 2

Point 1 to select specific files to download will be trickier to solve but I think it can be done, but I'll give it a try after solving the other open issues.

Yes the ESPRESSO ones fail because there are no spectra. If you did a star with no HARPS or FEROS spectra a similar message would appear, but it wouldn' crash the program because of it
