Parse hexadecimal notation

[bfontaine]

Also, disallow 0-prefixed integers such as 0644 per the spec:

No integer other than 0 may begin with 0. 64-bit (signed integer) precision is expected.

I had to add a negative lookahead in the t_INTEGER regexp so that 0xABC is not parsed as 0 xABC. The current implementation allows an integer to be followed by a symbol or a keyword:

>>> edn_format.loads_all("123abc")
[123, Symbol(abc)]
>>> edn_format.loads_all("123NNN")
[123, Symbol(NN)]
>>> edn_format.loads_all("123:abc")
[123, Keyword(abc)]

The spec doesn’t explicitely say this is incorrect (emphasis mine):

Elements are generally separated by whitespace.

This fixes #62.
