Subject: ragel julia: upgrades tests to 1.0 of julia language

The string class is no longer containing uints, now signed. Convert the input
strings to vectors of uint8s, since the julia code generator currently supports
only uint8.

Use numerical representation of 'a' since we have no way to separate single
lits from double lits and cast them in the julia test case translator

Don't try to construct AbstractString, use String.

Array constructor Array{Int, 1}(undef, 20) must take undef as first arg.

Verify we have julia 1.0 or later in configure script.
