Saving a query with a bad name is allowed and breaks things

[tbertels]

After #224 got fixed, I migrated my saved queries to osm.org.
However, while doing so, I pasted the content of a query in the name field and saved it.
Result: queries saved on osm.org cannot be loaded anymore.

Possible causes:

• multiline name
• too long name
• special characters in name

Note that saving a query locally with a bad name prevents us to remove it, but other queries are still usable.

http://www.openstreetmap.org/api/0.6/user/preferences is still accessible and shows the saved preferences, so this doesn't seems to be an API bug.

would you mind posting the relevant output from your http://www.openstreetmap.org/api/0.6/user/preferences (the line starting with <preference k="overpass-turbo and having the "bad" name in it), so I can debug this a bit quicker? nevermind, fixed it already

PS: the queries saved from the "beta" instance will probably not be available on the "main" overpass-turbo.eu when the feature goes live there, because the two instances are using different namespaces for their settings.
