Settings of sql:connect overwrite defaults

[GoogleCodeExporter]

Using sql:connect overwrites the default connection settings, so repeatedly 
calling sql:connect assuming defaults will go wrong because it will use values 
set during previous calls to sql:connect.

For example:
Doing
sql:connect [["brand" "generic"] ["driver" "org.postgresql.Driver"] ["jdbc-url" 
"jdbc:postgresql://localhost/sqlwrappertest"] ["user" "test"] ["password" 
"testpassword"]]

and then
sql:connect [["database" "sqlwrappertest"] ["user" "test"] ["password" 
"testpassword"]]

This will connect to the postgresql database using the jdbc-url, not to the 
MySQL database as expected based on documented defaults

Clone() functionality used created a shallow copy of SqlSetting, and did not 
clone the internal settings HashMap

Fixed issue, added test to check for this behavior + minor refactoring to 
improve cohesion
