v1.2.5 - More flexible [-o/--option] config

--options are now able to be configured four different ways:

• [-o] → -o is the short name
• [--option] → --option is the long name
• [-o/--option] → -o is the short name, --option is the long name (this can also be [--option/-o])
• [-o/] → -o is the short name, the default long name is removed.

Additionally, there are now warnings if this sort of format is incorrectly specified.
