e8ec820d2e vm: add unload command
When execution fails it's the only way to change the prompt showing the
last executed instruction. Example:

```
NEO-GO-VM > loadgo examples/engine/engine.go
READY: loaded 117 instructions
NEO-GO-VM 0 > run
Error: at instruction 3 (SYSCALL): failed to invoke syscall 805851437: syscall not found
NEO-GO-VM 8 > parse
Error: missing argument
NEO-GO-VM 8 > parse 123
Integer to Hex			7b
Integer to Base64		ew==
String to Hex			313233
String to Base64		MTIz

NEO-GO-VM 8 > unload
NEO-GO-VM > exit

```

e7a0ecb349 compiler: provide .go filename to Compile
First argument contains filename, thus we use '.go' suffix to
distinguish between directories and files.
Contract name should be provided in options.

8af9c870b1 compiler: remove CompileWithDebugInfo
It is a simple wrapper over `CompileWithOptions` which we don't really
need. Custom options can be specified explicitly instead of using some
random default. This default was introduced in 1578904da, however tests
written there use `CompileWithOptions` and all other tests
pass on that commit even without this default.

51127b8918 vmcli: convert base64 string to address in parse
In application logs hashes are serialized as base64 so it is useful
to convert them back to address via `util convert`.
