[arch-dev-public] .so bump - icu 4.2

I'm just loading new icu up to testing. This will requiere rebuilds (from our packages webside):

* brltty * go-openoffice * libflashsupport * libwebkit * openoffice-base * openoffice-base-beta * openoffice-base-devel * tin

I'll do the rebuilds one by one. This will take some time especially for the OOo packages...

Please report if more packages will need a rebuild.
