[2.1]: Trailing slash in new theme path should be removed

[asmith20002]

Basic Information

Apologies this is a minor bug. When submitting a new theme by specifying its folder path, if the path ends with "/", it gets saved in the database with that slash. The problem arises when SMF tries to minimize CSS files. For example the path to sprite images could get messed up.

Correct example (when there's no trailing "/")

div.sceditor-grip, .sceditor-button div {
  background-image: url(../../default/images/icons/editor_sprite.png);
  background-repeat: no-repeat;
  width: 16px;
  height: 16px;
}

Incorrect example (when the theme path ends with "/")

div.sceditor-grip, .sceditor-button div {
  background-image: url(../../../default/images/icons/editor_sprite.png);
  background-repeat: no-repeat;
  width: 16px;
  height: 16px;
}

It adds an extra "../" to the sprite path.
