Spring update 0.82.1339 general fixes, optimizations and enhancements

Follow update instructions at:

http://www.sachse.embl.de/emspring/install.html#update

The following programs are affected:

1. SEGMENTREFINE3D:

Fixes for data sets with large number of asymmetric units

Fix/workaround for occasional database lock problems on cluster mounted nodes

Fix in ‘Absolute limit of x and y-shifts’ handling. Now properly respects this.

Declared some options as experimental: support remains limited.

Occasional over-estimation of FSC fixed due to densities at upper and lower ends of filament

Implementation of ‘independent half-set’ refinement (a.k.a. gold-standard refinement) 

Note: the update will break reading your previous refinement.db files

Database files can be updated as follows:

% spring -udb=refinement.db -inp=refinement024.db -out=refinement024_up.db

2. SEGREFINE3DINSPECT:

Additional option of signal-to-noise weighting using FSC file.

3. SEGLAYER2LATTICE

Simulation of layer-line pattern takes rotational symmetry into account
