Read of coll par line in molinit can overflow

[allegroLeiden]

Thanks to @dquenard for raising this.

In molinit.c line 192 the comment string for a collision partner is read. The read is 80 characters long (although the array is dimensioned to 200), but some comments can be longer than this, eg in the LAMBDA database file for CH2: http://home.strw.leidenuniv.nl/~moldata/datafiles/c2h_h2_e.dat. Lime seg faults when it tries to read this line.

The seg fault actually occurs a bit later because the buffer overflow causes Lime to read the wrong value for the number of temperatures, and everything goes downhill from there.
