Add a QVariant cookie to HgTask to be emitted on successful
execution, wired to IVersionControl.

the new approach makes it possible to use more edit features
inside the rename selection like cut/copy/paste. Furthermore
it compresses rename operations better on the undo stack.

...making use of the new code model features. Move code to
separate file. Make it possible to obtain path to generated

When auto-indent is turned off, Qt Creator uses a simplistic approach of
copying the indentation string from the previous line. This was broken
when the cursor was positioned inside the indentation, since this caused
part of the indentation to go to the next line, which was then prepended
with the copied indentation, in effect increasing the indentation for
each new line.

The solution here was to copy the indentation from the previous block
only after inserting the new block, which causes the indentation of the
previous line to be cut off by exactly the right amount to keep the
indentation constant.

aborts when part of the selection is outside of the name. Previously, a
selection could cause the text to get inserted backwards.
