Scayt options dialog doesn't work with prototype.js enabled environments

[Antti Leppä]

When using CKEditor in prototype.js enabled environments SCAYT plugin options dialog opening crashes.

This is caused by plugins/scayt/dialogs/options.js:218

for ( i in buttons )

Normally this clause iterates over all items within a array but in prototype enabled environments this causes loop to iterate also over all extended methods thus causing following doc.getById( button) to fail

This problem can be fixed by changing line 218 into:

for ( i = 0; i < buttons.length; i++ )

The problem was discovered with Prototype 1.6.1
