All ints are parsed in base 10

[qzb]

Octal and hexadecimal numbers are partially supported (by scanner), but always parsed in base 10.

Expected:

fmt := import("fmt")

fmt.println(0123)  // 83
fmt.println(123)   // 123
fmt.println(0x123) // 291

Actual:

fmt := import("fmt")

fmt.println(0123)  // 123
fmt.println(123)   // 123
fmt.println(0x123) // 0
