Build all Dendrite commands

Dendrite has numerous utility commands in addition to the actual server binaries. Build them all from the root of the source repo with:

go build -o bin/ ./cmd/...

The resulting binaries will be placed in the bin subfolder.

You can install the Dendrite binary into $GOPATH/bin by using go install:

go install ./cmd/dendrite

Alternatively, you can specify a custom path for the binary to be written to using go build:
