Cacti导入模板报错 Error: XML: Hash version does not exist.

将新版本到处的cacti模板导入到旧版本的时候，就会报Error: XML: Hash version does not exist.，
解决的办法是修改xml里面的相关hash值就可以了。

以下是cacti xml hash的一些说明：

Take the following example: <hash_04 0018258d1c9487a6c58dd804f4a012007664>
The first 2 digits are the type of the template.
The next 4 digits are the Cacti version it was created on.
The next 32 digits are a random number.

"0.8.4"  => "0000",    
"0.8.5"  => "0001",    
"0.8.5a" => "0002",    
"0.8.6"  => "0003",    
"0.8.6a" => "0004",    
"0.8.6b" => "0005",    
"0.8.6c" => "0006",    
"0.8.6d" => "0007",    
"0.8.6e" => "0008",    
"0.8.6f" => "0009",    
"0.8.6g" => "0010",    
"0.8.6h" => "0011",    
"0.8.6i" => "0012",    
"0.8.6j" => "0013",    
"0.8.7"  => "0014",    
"0.8.7a" => "0015",    
"0.8.7b" => "0016",    
"0.8.7c" => "0017",    
"0.8.7d" => "0018"   
"0.8.7e" => "0019"   

For the example above, this template was exported with Cacti 0.8.7d.

所以需要导入新版cacti模板的时候，只需要修改hash里面的version相关字段即可。
