Add button to retrieve more/all rows, and refresh result

[SanjulaGanepola]

Changes

As of right now, users have to scroll to the bottom of the results panel to load more results. Several users have reported that this has been an issue. Although I haven't found an exact fix to the scrolling issue, I was able to reproduce the issue on my end by zooming in (quite a lot!). As a work around and nice feature, I thought it would make sense to add a button to Retrieve More Rows. The button should only be enabled when there are more rows to fetch.

Fixes #509
Fixes #470
Fixes #341
Fixes #287

How To Test

1. Run a query with more than 100 rows and verify the new button works in fetching more rows.
2. Run a query with less than 100 rows (or repeat step 1 until all rows are retrieved) and verify the new button is disabled.
3. Run a query, use the Clear Results (button beside it) and verify the new button is disabled.

Hello,
Tested with file that had 999 records.
At EOF button "Retrieve more rows" is disabled.
Clicking on "Clear Results" button "Retrieve more rows" is disabled too.
Thanks

Instead of "More" rows, why not have the control retrieve "All" rows... like ACS's RSS.

[Apsoftbe]

Maybe it can be interesting to have a parameter
To define "Number of rows" to retrieve at a time

[forstie]

Right, similar to ACS

@Apsoftbe @forstie Thanks for the input! I went ahead and implemented those suggestions. This is ready for review/testing.

Added a Retrieve... submenu with 2 options:

You can also configure the number of rows to fetch in the settings:

I also added a Refresh button:

This PR is on fire!

Everything worked well for me.
I did wonder if we should put guardrails on the settings to protect the user from themselves...?

Otherwise, ship it and way2go!

Good catch on adding the guardrail, forgot about that. Got that in!
