Regression from commit 6e61ecd0 (Merge
back branch alg_writerframes to trunk, 2014-03-19), the problem was
while SwFrameShell::Execute() was modified to put the various pool items
related to fill types (colors, gradients, etc) to the item set of the
dialog, the same was missing in SwTextShell::ExecInsert(), so colors
were missing on inserting a new frame, but not when editing an existing
one.
