This patch includes a number of very trivial consistency and language fixes:
- Standardize collie error messages printed to stderr to begin with a
initial capital like other standard unix tools and the C library.
(Messages written to the sheep.log are already standardized to be
uncapitalised.)
- Ensure all error messages are printed to stderr not stdout.
- Fix some awkward wording, typos and grammatical issues in the messages.
- Arrange for all of the tabular output from different collie commands to
be similarly formatted and headings capitalised.
- Spell VDI as 'VDI' not 'vdi' nor 'Vdi' in messages and comments.
