[Seaside] loading Seaside 3.0.6.3 in Pharo 1.4

[Esteban Lorenzano]

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
