* Swapping enableForOther locked input-field from disabled to readonly. No need to block users from selecting the text inside, only block editing it field.
* On top of that, also using javascript to hide the input-field if/when not needed, untill needed (PHP has a backup check to only use this value if the radio-button was on 'other')
* Escaping special html characters in the attributes. The message for .mw-help-field-hint contained the phrase "  content pages, in a "'''project namespace'''".  " which (raw, unescaped) ends the attribute right after the "a". Fixed now.
