Import host information from lower version of CM

User's scenario:

1. Click menu: file->import host list
2. Popup dialog
3. select CM paogram path in dialog
4. click OK to import

Fix it in version CUBRID Manager 8.4.0.2003 and CUBRID Query 1.2.1.0003
Solution:
1. In CUBRID Manager
Add menu [File->Import Hosts...] in CUBRID Manager.
Open the dialog,select CUBRID Manager workspace directory.
2. In CUBRID Query Browser
Add menu [File->Import Connections...] in CUBRID Query
Open the dialog,select CUBRID Query Brwoser workspace directory.

Test scope:
(1)Need test CUBRID Manager version 8.2.2~8.4.0, can import hosts related all configuration information
(2)Need test CUBRID Query Brwoser version 1.0.0~1.2.1, can import conncetions related all configuration information.

In CM 8.2.2.9008
1 modify file/preferences/query options. Modified the parameters like attachment.
2 Add host, add localhost PC's ip(such as:10.34.63.12)

In CM 8.4.0.2005
1 Import hosts. choose the workspace which created in CUBRID 8.2.2.9008

Actual result:
Right click host(10.34.63.12) in CM 8.2.2.9008,the content is same as attachment.
Right click host(10.34.63.12) in CM 8.4.0.2005, the content is default. it is not same as CM 8.2.2.9008

When import host, group change has error.

1 if we hasn't configure group in target CM,after import host, the host which has been put into group can be redistribution.

2 If we has configure group in target CM. such as
localhost in group1
10.34.63.13 in group2
Group in source CM:
localhost in g1
10.34.63.13 in g2
After import host:
group1 localhost
group2 10.34.63.13
g1 localhost
g2 10.34.63.13

expect result:
group1 localhost
group2 10.34.63.13

Fix it in CUBRID Manager 8.4.0.2011 and CUBRID Query Browser 1.2.1.0011

When we hasn't configure group in target CM, After import host, the group has import, but the group is empty.
