fixed #99 (Corpus explorer does not output alignment edges with no annotations)
first step for transforming CorefVisualizer from AOM to Salt: compiles
more conversions from long to string IDs and fixed all current warnings in CorefVisualizer
highlighting was not working since there were illegal characters (at least for jquery) in the ID
we also have to escape the "."
re-enabling the match colors in the CorefVisualizer

Now the matched nodes are no longer all red, but have the same color as in KWIC
sort token before iterating
output coref visualizations for each texts after each other

also remove some fuzzy "tooltip space" code
using the gagawa library to create well-formed HTML
only output wrapper table when using multiple-texts
don't use the edge name but its type as type...
SRelation#getSName is not the component name
output proper doctype
use CSS for styling instead of HTML attributes
fixing endless loop caused by an error when adjusting the condition
automatic determine which texts to in include in CorefVisualizer
filter start nodes by triggered layer
array does not support remove
use actual annotations to determine if corefvisualizer should output text if "hide_empty" mapping was set to true
removing the unwanted characters from the Salt IDs was unexpected slow, use MD5 hash instead
