Fix for bug #24218 (https://gna.org/bugs/?24218).

This is the incorrect labelling of alignment tensors by the align_tensor.matrix_angles user function
when a subset of tensors is specified. The logic for the labels was expanded from being only for
all tensors to handling subsets.

Update the release checklist document.

The version number at http://wiki.nmr-relax.com/Template:Current_version_relax also needs to be
updated for each release.

A number of updates for the release checklist document.

This should make it easier to replicate the full release process.

Added some unicode characters for improved formatting of the CHANGES file.

Fix for a replicated title in the HTML manual causing two Frame_order.html files to be created.

Ported r28149 to r28151 from the trunk to improve the HTML manual.

The command used was:
svn log -r28149:r28151 svn+ssh://bugman@.../svn/relax/trunk .

Avoidance of a replicated title in the frame order chapter of the manual.

The replicate title finding script now processes short titles as well.

This shows that the Frame_order.html file will be conflicting and overwritten.

Improved formatting for the \yes LaTeX command for the HTML manual (www.nmr-relax.com/manual/).

This now inputs the raw HTML character for a tick.

Updated the relax version number to 4.0.1 on the http://www.nmr-relax.com/api/index.html webpage.
