Add five new functions to deal with date calculation and timing:
- localtime(), gmtime() - return a broken down calendar date and time
specification from the given epoch (or now, if absent) in local and
UTC time respectively
- timelocal(), timegm() - the inverse operation for the former functions,
taking a date and time specification (interpreted as local or UTC time
respectively) and turning it into an epoch value
- clock() - return the second and nanosecond values of the system clock,
useful for time/performance measurements

A typo in the custom order function of the test case caused the test case
to yield differently sorted results on OS X, triggered by differences in
the libc's `qsort()` implementation.

- Let `require()` always evaluate the executed code in raw mode
- Let `render()` always evaluate the executed code in template mode
- Let `include()` inherit the raw mode semantics of the calling scope

The most common usecase is extracting the value of a single byte at a
specific offset, e.g. to scan a string char-by-char to construct a hash.
Furthermore, constructing an array which contains the results of multiple
`ord()` invocations is trivial while efficiently extracting a single byte
value without the overhead of an intermediate array is not.
Due to that, change `ord()` to always return a single integer byte value
at the offset specified as second argument or at offset 0 in case no
argument was supplied.
That means that `ord("Abc", 0, 1, 2)` will now return `65` instead of the
former `[ 65, 98, 99 ]` result.
Code relying on the former behaviour should either perform multiple calls
to `ord()`, passing different offsets each time or switch to the `struct`
module which allows efficient unpacking of string data.
