remove CRLF line endings as well as whitespace on line endings

TODO.txt was CRLF (copied over from Windows) - after having opened
that file, DOS linebreaks seemed to infect every other edited Java
file O_o
add JAR export targets
suppress warning

any ideas on how to get this right?
switch back to tabbed layout
remove unneeded imports
don't break on initialisation if source file is not available

point of the UI is to let the user change the input file to something
other than the default
add small deploy script

and rename other helper script
