Consider providing man pages

[hosiet]

Man page is not a "must-have" for this project but it doesn't do any harm too. Please consider installing it into UNIX-like systems when doing "make install".

(Also consider installing icons into /usr/share/icons/ please.)

Proposed example man page (danmaQ.1):

.\"                                      Hey, EMACS: -*- nroff -*-
.\" (C) Copyright 2017 Boyuan Yang <073plan@gmail.com>,
.\"
.TH DANMAQ 1 "2017-10-17" "Tsinghua TUNA Association"
.\" Please adjust this date whenever revising the manpage.
.\"
.\" Some roff macros, for reference:
.\" .nh        disable hyphenation
.\" .hy        enable hyphenation
.\" .ad l      left justify
.\" .ad b      justify to both left and right margins
.\" .nf        disable filling
.\" .fi        enable filling
.\" .br        insert line break
.\" .sp <n>    insert n+1 empty lines

I'm not familiar with CMake thus not providing patch for CMakeLists.txt here.
