Move HawkEye project version Java constant to hawkeye-core

[tisonkun]

It's now under hawkeye-command but it should be in the core module for any other modules usage.

hawkeye/hawkeye-command/src/main/java/io/korandoru/hawkeye/command/CommandConstants.java

Lines 24 to 40 in e75b11d

	public final class CommandConstants {
	public static final String UNKNOWN = "<unknown>";
	public static final String VERSION;
	static {
	ClassLoader classLoader = CommandConstants.class.getClassLoader();
	try (InputStream is = classLoader.getResourceAsStream("hawkeye.properties")) {
	final Properties properties = new Properties();
	properties.load(is);
	VERSION = properties.getProperty("project.version", UNKNOWN);
	} catch (IOException e) {
	throw new UncheckedIOException("cannot load hawkeye properties file: hawkeye.properties", e);
	} catch (Exception e) {
	throw new UncheckedIOException("cannot load hawkeye properties file: hawkeye.properties", new IOException(e));
	}
	}
	}

This should also fix a bug that:
