dry-wit 3 is out

I've decided to wrap the current state of dry-wit as a new version. I've finished some initial tests and now I'm confident dry-wit scripts can now run other dry-wit scripts without conflicting each other.

As before, the API documentation is available here.

Release notes

Stateful modules:
- Each module that needs its own variables can now define them using DW.declareGlobalString, DW.declareGlobalInt, DW.declareGlobalArray, DW.declareGlobalMap.
- They're expected to provide an unique name, to avoid variable name conflicts. Usually, it'll be provided by [module].getModuleName() function.
- For string or int variables, you can retrieve the variable value by just doing something like:
```
[module].getModuleName;
DW.getGlobalString "${RESULT}" MY_VARIABLE;
```
- For array or associative arrays, you can retrieve the variable value similarly:
```
[module].getModuleName;
DW.getGlobalVariableName "${RESULT}" MY_ARRAY;
local -n myArray=${RESULT};
```
- For string or int variables, you can set a new value with:
```
[module].getModuleName;
DW.setGlobalString "${RESULT}" MY_VARIABLE "new-value";
```
- For array or associative arrays, you can change its contents with:
```
[module].getModuleName;
DW.getGlobalVariableName "${RESULT}" MY_ARRAY;
local -n myArray=${RESULT};
myArray[0]='hello';
myArray[1]='world';
```
