- move cli files from `cli/drone` to `cli/`
- move cli main to `cmd/cli/main.go` to match agent and server
- use version from `version/version.go` to match agent and server
Before cold and hot runs are the same:
```
$ rm -rf $GOPATH/pkg
```
```
$ time make
go generate github.com/drone/drone/server/template
go generate github.com/drone/drone/store/datastore/ddl
go build --ldflags '-X github.com/drone/drone/version.VersionDev=' -o release/drone github.com/drone/drone/drone
real 0m43.638s
user 0m48.990s
sys 0m5.480s
```
```
$ time make
go generate github.com/drone/drone/server/template
go generate github.com/drone/drone/store/datastore/ddl
go build --ldflags '-X github.com/drone/drone/version.VersionDev=' -o release/drone github.com/drone/drone/drone
real 0m46.950s
user 0m49.506s
sys 0m6.086s
```
After hot builds are much faster:
```
$ rm -rf $GOPATH/pkg
```
```
$ rm -rf $GOPATH/pkg && time make
go generate github.com/drone/drone/server/template
go generate github.com/drone/drone/store/datastore/ddl
go install -ldflags '-X github.com/drone/drone/version.VersionDev=' github.com/drone/drone/drone
cp /Users/bobrik/projects/drone/bin/drone release/drone
real 0m44.735s
user 0m51.049s
sys 0m4.517s
```
```
$ time make
go generate github.com/drone/drone/server/template
go generate github.com/drone/drone/store/datastore/ddl
go install -ldflags '-X github.com/drone/drone/version.VersionDev=' github.com/drone/drone/drone
cp /Users/bobrik/projects/drone/bin/drone release/drone
real 0m3.364s
user 0m2.934s
sys 0m0.808s
```
Currently the archive gets created including the directories, so the
regular guide to just download and copy the binary doesn't work. With
that change I have dropped the folders from the archive and the Drone
binary gets directly into the toplevel of the archive.
