Add alt code to 2012/omoikane + try + formatting

Browse Source 
There are two alt versions which should be useful for (respectively)
those who do not have /dev/urandom and those who use Windows. Both of
these versions read from argv[0] instead of /dev/urandom but the second
one sets binary mode on stdin and stdout. This is to be consistent with
the fact that other entries also have this as an alt version.

The try.sh and try.alt.sh scripts work on the entry and the first
version of the alt code, the one that is not Windows specific. The
scripts consist of commands from both the to use section of the
README.md (which is still there) and the try section (which now refers
to try.sh).

Format/typo checks in README.md file.

There is an alternate version that will read from the compiled file itself, in

NOTE: if your OS does not have `/dev/urandom` then you should specify a seed
file or use the [alternate version](#alternate-code) which reads in the compiled
binary itself.
### Try:
```sh
echo "A quick brown fox jumps over the lazy dog" | ./nyaruko > output.c
perl output.c > data.c
cc -o data data.c
./data
cc -o output output.c
./output
./try.sh
```
The script [try.sh](try.sh) will check if you have perl before trying to use the
perl parts of the script.
## Alternate code:
The alternate version will, if no file is specified, read in the compiled binary
itself rather than trying to open `/dev/urandom`, which is the default for the
original entry. This is useful if your system does not have a `/dev/urandom`
file and you do not want to specify an extra file. The second alternate version
is like the first except it also should theoretically work with Windows, setting
binary mode on `stdin` and `stdout`.
### Alternate build:
For the first version:
```sh
make alt
```
For the second version:
```sh
make alt2
```
### Alternate use:
Use `nyaruko.alt` or `nyaruko.alt2` as you would `nyaruko` above.
### Alternate try:
For the first alternate version:
```sh
./try.alt.sh
```
We have no way to test the second version, sorry (tm Canada :-) )!

except that it also sets binary mode on `stdin` and `stdout` which should
theoretically make it work in Windows.
