Make list of ignored syntax groups configurable

While trying to fix issue #20 I decided to refactor the code that

it turned out that including shFunction* in the list of excluded
syntax groups didn't fix the reported issue...

 ## Faster syntax highlighting using Python
 
 The Vim script implementation of dynamic syntax highlighting is quite slow on large tags files. When the Python Interface to Vim is enabled the easytags plug-in will therefor automatically use a Python script that performs dynamic syntax highlighting about twice as fast as the Vim script implementation. The following options are available to change the default configuration.
