incorrect markup for tooltips in finddialog

Too many <ul>, doesn't look nice...

commonui/finddialog.cpp line 136 and 153:

<qt>
<p><b>Options</b></p>
<p>Here you can finetune replacing:
<ul>
<li><b>Case sensitive</b>: does case of entered text have to be
respected?</li>
<ul>
<li><b>Only whole words</b>: text found must not be part of a longer
word</li>
<ul>
<li><b>From cursor position</b>
: start replacing at the part of the document where the cursor is. Otherwise
replacing is started at the beginning or the end.</li>
<ul>
<li><b>Find backwards</b>: Should be self-explanatory.</li>
<ul>
<li><b>Use regular expression</b>: use text entered in field <b>Find</b> as
a regular expression. This option has no effect with the replace text,
especially no back references are possible.</li>
<ul>
<li><b>Ask before replacing</b>: Enable, if you want to have control about
what is replaced. Otherwise all found text is replaced without
asking.</li></ul></p></qt>
