v2.0.1

• fixed negative numbers in the template throwing an error – this happened, for example, when using {{ replace("My Name Is", " ", "_", -1) }} which would error (the last parameter of Go's replace function denotes the maximum number of replacements to perform, -1 being unlimited) – fixed in fd3b9c0
• added {{ includeIfExists(templateName) }} function that doesn't throw an error if the template to include doesn't exist (useful for dynamic template files to include); it also has a second form where you can use the boolean return value to print something else if the template couldn't be found – documented here, added in 9a0ef3b
