修改powershell颜色

默认的powershell启动时加载配置文件可以在以下路径中寻找，如没有 PowerShell_profile.ps1 或者 Profile.ps1 在相应的路径下新建即可。

$Home：当前使用者的主目录
$PsHome：存放 Windows PowerShell 的目录

# 当前用户，所有主机有效
$Home\Documents\Profile.ps1
# 当前用户，当前主机有效
$Home\Documents\PowerShell\Microsoft.PowerShell_profile.ps1
# 所有用户，当前主机有效
$PsHome\Microsoft.PowerShell_profile.ps1
# 所有用户，所有主机有效
$PsHome\Profile.ps1
