New issue 5416 by [hidden email]: Improve MC version loading
http://code.google.com/p/pharo/issues/detail?id=5416

- don't serialize versions again, simply fileout the downloaded version file
- speed up categories: updates by using an intermediate Set for fast  
includes check
- don't open the source-file twice when reading the timeStamp AND the  
source for MCMethodDefinition

SLICE-Issue-5416--Improve-MC-version-loading-CamilloBruni.9

- weakly caching MCMethodDefinitions in RBMethodDefinition
- directly cache downloaded mcz
- Gofer does direct file-checks for mcz instead of walking over the whole  
file list
- always use the MCCacheRepository when loading from a remote location  
(this might have some side-effects)

these changes finally take advantage of having a package-cache. with a pre  
filled package-cache updating a pharo system is going to be roughly 5-times  
faster.

set for the final change test

updated for the lates pharo version. However:

I introduced getSourceCodeFromFIle: on CompiledMethod again, as an  
extension package to Ring-Core. Since I figured out that one can speed up  
the MC definition creation a bit by not opening the source file stream  
twice (timeStamp and sources)...
