Minor changes
Merge branch 'mavenise' of https://github.com/friesey/PdfEventPrep into mavenise
Asserted java7 in pom
In "PdfAValidator" the two txt-files with the findings were not closed, added:

ShortSummary.close(); and outputfile.close();
Changed the try/catch block in "PdfUtilities.brokenPdfChecker"-method to a more general Exception as some really broken PDF-files can cause all kinds of Exceptions which will otherwise lead to a crashing of the program.
As the function PdfUtilities.brokenPdfChecker causes crashes, it is not used by any of the tools now and has a TODO as a reminder that something is wrong with it.
The txt-outputfiles in PdfAValidator closed at the wrong place. Fixed.
Eliminated fishy XML Output in "PdfHeaderChecker"
Change the fixed path to the findings-outputfile in PdfTwinTest to a folder selection by the user of the tool.
PdfTwinTest: Resolve Error if no folder was chosen
