Working directories are now set seperately from the commands so they
can later be swapped out when running linters over projects is
supported, and also better support filename mapping for running linters
on other machines in future.
Allows the user to override $GO111MODULE environment variable through
ale options. This gives control over the default behavior of Go module
resolution.
Golang documentation:
https://github.com/golang/go/wiki/Modules#how-to-use-modules
Add `ale#Go#EnvString()` function to make it easy to add similar Go
environment variables in the future.
Use the new `EnvString` function in all available Go tools callbacks
& update tests
Also add test of linter command callback for `gofmt`
When using `gotype` without the `-e` option, it will only output the
first 10 errors. When working on a larger package that ofter means taht
those 10 errors are in other files then the one that you are currently
working on which then seems to indicate that there are no errors.
By adding the `-e` flag, all errors will be returned and shown properly
in the file that you are working on.
