update gulpfile for js output minified or not
added test for tableComplexExample
added tableComplex2Example with only one table
trying to correct bug
corrected bug-#12

The solution was the following:

returning the result of subfile.applyTags() instead of subfile itself (so
the recursion works better)
gulpfile uglify again
Merge branch 'bug-#12'
