Fix for bug #7675. Removes unneccessary lookup of pdb.load_seq

https://gna.org/bugs/index.php?7675

Modified 'self.vectors()' to place the proton and heteronucleus name in 'self.relax.data.res[run]'.

Previously the names were being placed into 'self.relax.data.pdb[run]' which is problematic for
task #3838 (https://gna.org/task/?3838). This is also preventing the resolution of bug #7544
(https://gna.org/bugs/?7544).

An attempt to change the shared library suffix from '.dylib' to '.so' on Mac OS X.

This problem was reported by Douglas Kojetin <douglas dot kojetin at gmail dot com> at
https://mail.gna.org/public/relax-users/2006-11/msg00002.html (Message-id:
<AD17DD2D-A37B-44D4-B1B8-1A2349EC7EC5@...>) and as bug #7670 (https://gna.org/bugs/?7670).

To use a different suffix, I have explicitly set the 'SHLIBSUFFIX' environmental variable to '.so'.
This should overwrite the SCons default of '.dylib'.

An attempt at removing the '-dynamiclib' gcc option when compiling the C modules on Mac OS X.

To remove the '-dynamiclib' option, I replicated what Doug had done in his post at
https://mail.gna.org/public/relax-devel/2006-11/msg00098.html (Message-id:
<0E180DBB-896A-45F6-B19D-D6A02FD2BA4A@...>). Rather than changing the line:

env['SHLINKFLAGS'] = SCons.Util.CLVar('$LINKFLAGS -dynamiclib')

in the SCons sources, I have replicated Doug's modification within the relax 'sconstruct' script.
This change needs to be tested.

Deletion of the 'macraild' branch.
