Removed the patch for the Outline object since this is now supported by Prawn itself
Added Ruby 2.1.0 to tested versions
Using the newer prawn versions now
Mitigated a performance regression due to the introduction of the location information

Performance of kramdown on Ruby 2.0 and 2.1 got 4x resp. 3x
worse due to storing of the location information. Prior
Rubies are not affected that much.

With this fix, performance is only 2x worse on Ruby 2.0 and
0.5x on Ruby 2.1
Added prawn as development dependency
Updated performance graphs
Updated release notes, version and homepage
Some small performance optimizations
Extracted setting of pre-defined link definitions into method

This will allow applications to cache already normalized link
definitions, for example.
Updated copyright year to 2014
Small string performance optimization
Updated release notes, version and homepage
Fixed PDF tests for Ruby < 1.9
Don't install prawn for travis on ruby < 1.9
Hopefully final fix for travis.ci
Fixed travis.ci
