Updated README.md files to represent current code / use Markdown format

Previously, all of the README files have been renamed to README.md
and now, the contents of these files were changed to use Markdown
format. Other than format inconsistency, some README.md files lacked
information about modules, or were out of date. By using LibreOffice
/ OpenOffice wiki and other documentation websites, these files were
updated. Now every README.md file has a title, and some description.
The top-level README.md file is changed to add links to the modules.
The result of processing the Markdown format README.md files can be
seen at: https://docs.libreoffice.org/

+## Testing
+### PostgreSQL
 
 For testing, use:
 
-podman pull postgres:latest
-podman run --name=postgres -e POSTGRES_PASSWORD=foobarbaz -p 127.0.0.1:5432:5432 postgres:latest
+    podman pull postgres:latest
+    podman run --name=postgres -e POSTGRES_PASSWORD=foobarbaz -p 127.0.0.1:5432:5432 postgres:latest
 
 In Base, Connect to an existing database, select PostgreSQL:
 
-URL: host=127.0.0.1 port=5432 dbname=postgres
-User: postgres
-Password: foobarbaz
-
-podman stop postgres
-podman rm postgres
+    URL: host=127.0.0.1 port=5432 dbname=postgres
+    User: postgres
+    Password: foobarbaz
+    
+    podman stop postgres
+    podman rm postgres
 
 In order to test SCRAM authentication, create the container like this:
 
-podman run --name=postgres -e POSTGRES_PASSWORD=foobarbaz -e POSTGRES_INITDB_ARGS=--auth-host=scram-sha-256 -e POSTGRES_HOST_AUTH_METHOD=scram-sha-256 -p 127.0.0.1:5432:5432 postgres:latest
