Limit field (ui_limit) not parsed correctly

Problem/Motivation

The ui_limit field can be submitted with different line endings depending on the platform of the client/browser. Display Suite calls explode("\n", ...), which leaves a hanging "\r".

Proposed resolution

Remove all "\r" before storing this field. Simple diff -u patch below:
