creep.say functions

[couchcactus]

added creep,say functions (not very good for low CPU)

[couchcactus]

not sure if it will be merged, there is promises in the code of low CPU optimisation, creep.say isn't very good for that

[couchcactus]

withdraw, transport, build, upgrade, attack, dismantle, power functions and etc now have creep.say functions

This change is a reasonable idea, but you need to make the change to the source of this repository. Adding this 11k line file won't change anything on the source.

Steps to modify the source:

1. fork the repo (on this page at the top right above the green code button
2. clone your fork git clone https://github.com/couchcactus/screeps.git
3. open the code in an editor (vscode, sublime text, notepad++...)
4. make your changes (only change files that end with .ts, everything else is autogenerated)
5. test your changes with npm test (see README.md for more info)
6. commit & push your changes
7. open github.com and open a pull request

If this sounds like a lot of work just to suggest a change, it is. But this will save you a lot of time in the future and help keep things organized.
