allow pipes

[tolot27]

As long as text search is not supported, STDIN or other named pipes (eg fqless <(fgrep 1234 test.fq)) would be really helpful just to inspect a single sequence or small subset very quickly.

It turns out that using pipes results in difficulties changing colors on the TTY. I did not find a solution that allowed for custom colors and pipe input. But I will be looking into it, maybe I'll find a solution.
