Small patch for tab label on Properties sheet.

[brickviking]

I have a small niggle I can provide a patch for; I can't provide a pull request as my forked version isn't on a public-facing github fork.

When I bring up the properties sheet for an icon, the tab says "Main", not "Properties", the following patch should correct this.

diff --git a/src/html/properties.html b/src/html/properties.html
index d4d0b87..1b0eb4f 100644

 				<tr>
-					<td class="TabButtonActive">Main</td>
+					<td class="TabButtonActive">Properties</td>
 					<td class="TabButton" style="display:none">Temp</td>
 					<td class="TabSpace"></td>
 				</tr>

I also have a question. What was the Temp tab meant to be for? I can't see anything that activates that tab, nor can I see any code that uses it.

Cheers, brickviking
