String.prototype.trim. (Closes #961) Note that we should also be more careful not to clobber other library prototypes. (See #962) I'm going to check this in to fix the bug for 2.5, and we'll work on the latter in 2.6. git-svn-id: http://svn.openlayers.org/trunk/openlayers@4213 dc9f47b5-9b13-0410-9fdd-eb0c1a62fdaf
