Update stand_alone_install.md

One grammar correction so I took the opportunity to insert a bunch of picky commas.

 By default, the Geodynamic World Builder is configured in `debug` mode, i.e., it includes several assertions to make sure that the input and computed properties (temperature or composition) are reasonable. This makes the program much slower in the `debug ` mode compared to the `release` mode (10 times or more depending on the problem type). It is therefore recommended that you first test the feasibility of the generated output using a small problem (lower resolution or lesser features) in the `debug` mode and then use the `release` mode to run the full-scale problem for faster computation.
