settings & readme

- slightly changed project settings
- emended README
v0.2.1 bugfixes

- finally (hopefully) found out how to set project up so that compilation with
  javac 1.6 results in a jar which can be run with `java -jar` (prior to that,
  main class could not be found; but strangely, double-clicking the jar
  worked...)
- fixed MAJOR problem which made TransVer not work on Windows---no colons in
  filenames there, apparently (I should have known...)
