feat: abbreviations

[TorchedSammy]

abbreviations are an alternative to aliases which are (short) words that are expanded when entered. this can be done on the space key or enter key (user selectable).

example:
if a user sets an abbreviation gp to be git push, when typing gp and then the space and/or enter key, it will expand to git push. this means the expanded form will be saved to history instead

I'm going to do this, do you have any recommendations? I haven't looked at the project code in a while

[TorchedSammy]

look at line 848 (seqAltDelete) which deletes a word. then you can just insert the expanded version. of course you have to check if the last word is a valid abbreviation.

ok, tomorrow I'll start doing that!
