Force break instead of paragraph on new lines in Tiny_mce
Normally tiny_mce inserts a new paragraph when you hit return. You can make tiny_mce force a BR element on newlines instead of inserting a new paragraph. Normally you should utilize P tags instead of BR, so only use this when you have to!
Usage:
tinyMCE.init({
force_br_newlines : true,
...
});
