Consistent use of capilalizaiton in output

[myurkin]

Currently, ADDA mostly capitalizes first letters in each new line (sentence) in the output (log and stdout), but several lines start with small letters. The change itself is pretty straightforward, but this cause many warnings in tests that compare the output, so this better need to be done before the release. Some changes in the manual and wiki pages may also be needed.

Also this may break backward compatibility for parsers, so at least the ones supplied with ADDA need to be updated (i.e., misc/parse_log).

In principle, this applies to other output files as well, but we need to consider them separately, whether there is any clear inconsistency inside one file.

This can be combined with other changes to text in the output, e.g., dipole -> voxel.
