Replaced JBang --option value with --option=value

[wfouche]

JBang versions after 0.138.0 do not support the previously "not officially supported but working anyway" way of specifying runtime options that JythonCli.java uses for readability purposes.

No longer can we specify options using the following syntax:

• --runtime-option -Dpython.console.encoding=UTF-8

The --<option>=<value> format must be used. The format changes to:

• --runtime-option=-Dpython.console.encoding=UTF-8

which can be shortened to :

• -R=-Dpython.console.encoding=UTF-8

The same update has been applied to options --deps and --main.

@jeff5 , jython-cli does not currently work with the latest release of JBang (0.139.3). This fix resolves the issue.

@jeff5 or @Stewori , jython-cli is broken without this PR if the latest version of JBang is used to run Jython. This PR is a simple change, it just defines the command-line parameters in a universally supported manner.

JBang 0.141.0 has just been released, and resolved this issue that this PR solves. PR no longer required.
