[igraph] Forbidden attribute names would be nice

As a way of avoiding typos, it would be nice if attribute names like "weights" were forbidden and  generated an error message. Because if I type for example E(g)$weights, I almost certainly mean E(g)$weight.  

It is a particular problem because many functions have an optional argument "weights" making it hard to remember when to use the singular and when to use the plural.

For example, the function "betweenness" has an optional argument "weights" (plural) the default for which is the weight (singular) edge attribute.
