New package added: icu4c

Finally, after being requested in LQ, Pat decided to add icu4c into Slackware-Current and this will enable him to build kexi in Calligra suite. This batch of update also upgrade poppler to 0.20.2, the minimum version which is required to have Okular to save a PDF including its annotations according to Eric on his blogpost about KDE 4.9.0.

Several other packages are rebuilt due to patches here and there such as util-linux, mysql, calligra, okular, and tumbler. Two packages are upgraded: cups and libwpg.

Java SlackBuild is also rebuilt to fix a typo in the code which resulted in dangling symlink
