release-0.6

This release updates the bundled goserver command to be fully standalone, and relocatable, because the file that it servers is now embedded inside the binary via implant.

In addition to being relocatable the goserver now also includes some simple example-scripts which make it easier to see how you might use it.

The core basic-interpreter gained the ability to use AND and OR inside conditional-tests, and also the ability to use AND, BIN and OR as operators themselves. These are demonstrated in the examples:

• Using OR in a conditional
• Using AND, BIN, and OR

There were some minor bugfixes made, for example in the case of a FOR loop where the starting index and terminating index are identical only one iteration will be made, rather than an infinite number. Handling GOSUB inside an IF statement also works correctly now.
