Added -m and minor changes.

Added -m flag, removed unnecessary parameter bIsPM and fixed 'New %s'.
The extra space here will affect the notifications for items which do not have a sub-category; such as _News_ or _Guest Book_. Use two templates instead?

```Lua
tTemplates = {
  sNotify = "New: %s has been added to [ %s ] table. Use %s for more information.",
  sCategNotify = "New %s: %s has been added to [ %s ] table. Use %s for more information.",
}
```
