Replace all only searches to the end of the document

[damo]

When using replace all in a document and the cursor was placed in the middle of the document, the search only replaces those instances between the cursor and the end of the document.

Two updates, now with Match cyclic checked:

1. The replace action will happen within full document;
2. The find action will automatically start from document start without an 'alert' stopping.

It would be better if this fix could be limited to the reported case, not changing the current "cyclic" behavior for find and replace.

Now the replacement will happen at whole document range independent of cyclic.

Please remember to commit #3757 as well as replace is totally broken without it.

Fixed with [3707].
