aria2 1.18.2 released

aria2 is a lightweight multi-protocol & multi-source, cross platform download utility operated in command-line. It supports HTTP/HTTPS, FTP, BitTorrent and Metalink.

This release fixes the wrong handling of return value of fork(), which
leads to high CPU usage. The progress readout has some color output.
Mingw32 build now receives colorized output. Mingw32 build now can
read unicode command-line arguments. The build script of OSX was
rewritten. The --bt-max-open-files now limits the number of opened
file globally for multi-file downloads instead of per download basis.
