first try for a gramma for the HTML visualization input files
some test config files and enhanced (still not complete) grammar
functioning value parsing (and test adjusted)
test more informations from the parsing
move package
starting to work on the matcher/output code and extended the grammar to be closer to the second suggestion
refactoring the code to use a more general "matcher/outputter" pattern

This puts some logic into the parser and some helper classes that was in the visualization before.
preparation for outputting the tags
track qname of matched annotation
actually output something
allow loading absolute files
add a default CSS file and check if style is meant to be a class and not a style definition
always use the complete text
use panel to enable scrolling
allow to import files for a toplevel corpus and use the imported media_files for the HTML visualizer
smaller fixes
Merge branch 'refs/heads/master' into htmlvis
do not use fixed size for KWIC
type arguments needed to be adjusted as well
allow to output parser errors
