.so version number is 0.0.0

The version number of the .so library was not set in release 1.67, so it 
defaulted to 0.0.0.  This causes link problems with any application that 
requires a version number larger than 0.0.0.

Note also that the .so library version number is not supposed to correspond to 
the release number.  Guidelines for setting the .so version can be found here:

    http://sourceware.org/autobook/autobook/autobook_91.html#SEC91

The plan is for 1.68 to have version number 2.0.0.  It will then build
properly with any application that requires a version number less than or equal 
to 2.0.0.

The fix is to add this line to Makefile.am in the parent directory:

    liblept_la_LDFLAGS = -version-info 2:0:0
