----------------------------------------------------------------
Patch for 4.x that fixes the version handling.
I am not really happy, because Version.parse("4.0.0") now parses to
4.0.0-ALPHA, but this is how it was defined and written to index.
I have to check the codecs now, that they correctly detect 4.0 ALPHA/BETA
indexes (e.g., use the right version constant on comparing).
Another thing, theoretically, analyzers must use LUCENE_4_0_0_ALPHA to compare.
Another idea I had would be to add a method {{Version.isMinimumLucene4()}}.
