Dialog improvements

by Vincent (zuyin kang) for abiword

This idea wants to solve these two problems in Abiword: 1. Users can set table attributions(width, height, rotate-angle) preciously in table-setting dialog 2. Make Frame expandable when users enter extra line of text I would like to split this idea to two part： 1. Table Setting Dialog: including dimensions setting and 'rotate-angle' setting 2. Frame expandable, making Frame expandable when users enter extra line of text for the 'rotate-angle' setting issue, it is another GSOC topic, but if none deal with that, I can do this two topic together.
