Ubuntu添加Intellij IDEA启动器

1. 建立/usr/share/applications/idea.desktop文件。

2. idea.desktop文件内容以下：

[Desktop Entry]
Encoding=UTF-8
Version=1.0
Name=IntelliJ IDEA
GenericName=Java IDE
Comment=IntelliJ IDEA is a code-centric IDE focused on developer    productivity. The editor deeply understands your code and knows its way around the codebase, makes great suggestions right when you need them, and is always ready to help you shape your code.
Exec=/usr/local/lib/idea/bin/idea.sh
Icon=/usr/local/lib/idea/bin/idea.png
Terminal=false
Type=Application
Categories=Development;IDE

3. 更复杂的例子能够参照目录/usr/share/applications/下的其余desktop文件。
