[Pharo-project] loading Seaside 3.0.6.3 in Pharo 1.4

Hi, I loaded last version of seaside into a pharo 1.4 image. Everything looks working fine, but there a couple of fixes: 1) KomLogger>>#attachTranscript self detachTheTranscript. ^(self streams detect: [:ea | ea isTranscriptStream] ifNone: [nil]) ifNil: [self addStream: TranscriptStream new] "TranscriptStream" is not anymore on pharo and should be replaced with ThreadSafeTranscript 2) String>>#withBlanksTrimmed is deprecated, and now it should use #trimBoth how can I proceed to apply this fixes into seaside (without breaking other platforms)? cheers, Esteban
