Two minor bugs in blacksmith HTML (in General)

There's a minor bug in the HTML for the blacksmith.tcl page.

For armor, the <td> element for the upgrade costs is not closed. For example:

<tr>
<td colspan=2>A&nbsp;Pair&nbsp;of&nbsp;Leather&nbsp;Boots</td>
<td width=1% align=right>4</td>
<td><select ...>
<option value=7_0>+7&nbsp;($0)</option>
 <option value=8_18291>+8&nbsp;($18,291)</option>
 ...more options...
</select>
</tr>

For weapons, the <td> element for the to-hit upgrade cost is closed by a </tr> instead of a </td>. For example:

<tr>
<td>3,594&nbsp;Arrows</td>
<td align=right>8</td>
<td><select ... >
<option value=4_0>x5&nbsp;($0)</option>
<option value=5_22027>x6&nbsp;($22,027)</option>
 ...more options...
</select></td>
<td colspan=2 align=right><select ...>
<option value=4_0>+4&nbsp;($0)</option>
<option value=5_3938>+5&nbsp;($3,938)</option>
...more options...
</select></tr>
</tr>
