0.20.0 released

[jon-heard]

Of particular interest to users:

• This change requires an update to the library for compatability. If you update the plugin, but don't re-import the library, then the shortcut-file mythicv2 will contain errors.
• More info is now available to each expansion script. The "expansionInfo" variable is filled with it. One parameter in particular lets you cancel an expansion. For more info, check the readme section Getting info about the current expansion.
• Library importing now allows you to enter a custom path for where to put the library.
• A bug that removed backslashes from parameters in shortcut texts was fixed.
