TIKA-774: ExifTool Parser

[rgauss]

Contribution of tika-exiftool for review

[chrismattmann]

@rgauss the work here is fantastic. This really could easily replace the one I wrote. If you don't have time I'll go ahead and update the wiki (which is a necessary first step since we have that wiki page now) here: http://wiki.apache.org/tika/EXIFToolParser I think that we can merge this in 1.14

@rgauss I tried running this without exiftool installed, and I get:

Results :

Failed tests: 
  ExiftoolExternalEmbedderTest>ExternalEmbedderTest.testEmbedStandardInputStream:277->ExternalEmbedderTest.embedInTempFile:251 Cannot run program "exiftool": error=2, No such file or directory
  ExiftoolExternalEmbedderTest>ExternalEmbedderTest.testEmbedTikaInputStream:288->ExternalEmbedderTest.embedInTempFile:251 Cannot run program "exiftool": error=2, No such file or directory

Test failures. The tests need to pass without exiftool can you help?
