Prototype:
\$result = versioncmp(a, b)
Where a and b are arbitrary version strings
This functions returns a number:
* > 0 if version a is greater than version b
* == 0 if both version are equals
* < 0 if version a is less than version b
Example:
if versioncmp('2.6-1', '2.4.5') > 0 {
notice('2.6-1 is > than 2.4.5')
}
