and dialog line1 to message parameter rename.
The isPassword change likely bumps minimum version up to Kodi 18.
This can be worked around if desirable.
Note: This has a previously applied optimization of using a local cache.
Before:
```
458570 66.934 0.000 66.934 0.000 {method 'execute' of 'sqlite3.Cursor' objects}
246771 58.075 0.000 58.075 0.000 {method 'fetchone' of 'sqlite3.Cursor' objects}
```
After:
```
368883 66.220 0.000 66.220 0.000 {method 'execute' of 'sqlite3.Cursor' objects}
157084 58.160 0.000 58.160 0.000 {method 'fetchone' of 'sqlite3.Cursor' objects}
```
Once again, the number of calls to execute and fetchone are reduced but
the total time spent executing each is relatively stable.
Profiling has shown that there are many calls to sqlite3.execute and
fetchone which takes a signicant amount of time. A simple way of
reducing these is to swap the 2-stage init of table row data into a
unified add.
Applying this to add_set and add_country yielded these results:
Before changes
```
281784 7.054 0.000 7.054 0.000 {method 'execute' of 'sqlite3.Cursor' objects}
127443 1.114 0.000 1.114 0.000 {method 'fetchone' of 'sqlite3.Cursor' objects}
```
After changes
```
281714 7.492 0.000 7.492 0.000 {method 'execute' of 'sqlite3.Cursor' objects}
127373 1.217 0.000 1.217 0.000 {method 'fetchone' of 'sqlite3.Cursor' objects}
```
Note: The total time of fetchone has actually increased. I am hoping
this was an abnormality on my machine and the actual reduction in the
number of calls will permantly reduce this total time.
