Fix for #286 (Dashboard Re-skin: System and Settings > Permissions and Access > Allowed File Types)

app.css has the following rule:

.form-group .form-control {
	height:34px;
}

Preview with the above rule in place: http://puu.sh/9H0ax/6c09de82b1.png
Preview with the above rule disabled: http://puu.sh/9H0hy/3204c47faf.png

Preview if edits aren't enabled: http://puu.sh/9H0us/7b49eadef0.png

Bar, everything should be fixed and working.  I'll leave the app.css edits to you as I don't know what global effect changing these things will have!

Hope it's all OK.
