Version numbering for everything
* Turned all '0.1dev' tool version numbers to '1.0.0'. * Changed Stuttermark's version number from '1.5' to '1.5.0'. * Added version numbers to the visualisations. * Updated README.rst to include all tools, but removed the usage details of Stuttermark because it is highly impractical to include usage details for all tools in the README file. I'll leave that to the -h/--help option and the yet-to-write FDSTools User's Handbook.
