Tools:

Check for the text/plain mimetype and if true then mark it as
text dump.

(WTR::InjectedBundlePage::dump):

LayoutTests:

Unskipping http/tests/multipart/load-last-non-html-frame.php.
Now the result should match the expectation.

<br> does not get deleted when inlined after some non-textual content.

Source/WebCore: 

deleteSelectionCommand does not handle the case when a <br> element is
inlined after some non-textual content (input controls, image etc.).

When doing a back-delete at the start of a line following such a <br>
the two contiguous lines should merge and the <br> should get deleted.
Currently, even though the <br> is deleted, another placeholder <br>
is incorrectly inserted at the same point, thus effectively there is no
change.

We are incorrectly computing the inline <br> to be at the start of an
empty line even though the line is not empty.

Test: editing/deleting/delete-inline-br.html

* editing/DeleteSelectionCommand.cpp:
(WebCore::DeleteSelectionCommand::handleSpecialCaseBRDelete):
Adding a check to verify that the inline <br> is not on an empty line
if the end node is not a <br> element itself and it's previous sibling
is the start <br> element.

Basically we check whether there is another node (end node) following
the <br>, that the node is not a <br> itself, and that the end node's
previous node is the start <br>.

LayoutTests: 

* editing/deleting/delete-inline-br-expected.txt: Added.
* editing/deleting/delete-inline-br.html: Added.
Added a testcase that verifies that the caret is placed at the correct
position after performing a back-delete operation.
