1.0 release.

Removed tier categories from statfile for both characters and fights.
Statfiles from previous releases are not compatible with 1.0 and cannot
be imported.

SaltyStats Manager has been replaced with SaltyStats Console
(console.py). It can only read the statfile, not write to it. This means
that you cannot add characters, edit records, etc. However, you no
longer have to worry about messing up or corrupting the statfile if
running it the same time as the main program.

Bug fixes and improved error messages.

Added Readme.md.
