[AutoTimer & OpenWebif] tags join/separation space character issue

[wedebe]

Adding (for example) tags AAA and BBB CCC to an AutoTimer via OpenWebif saves correctly to autotimer.xml as

<tag>AAA</tag>
<tag>BBB CCC</tag>

However, the e2tags are ingested by OpenWebif as AAA%20BBB%20CCC -> AAA BBB CCC.

/autotimer/src/AutoTimerConfiguration.py:

		# Tags
		if webif and timer.tags:
			extend(('  <e2tags>', stringToXML(' '.join(timer.tags)), '</e2tags>\n'))
		else:
			for tag in timer.tags:
				extend(('  <tag>', stringToXML(tag), '</tag>\n'))
