1312cfe599 Add square brackets around the saved expression 
When saving a raster expression the generated expression didn't contain square brackets around the letters used for band identifiers. Sticking with the NDVI example:

```
("NIR@1" - "Red@1") / ("NIR@1" + "Red@1")
```

becomes

```
(a - b) / (a + b)
```

Due to the way the expression is parsed these would not be interactie parameters for the user to set as the parameters requre square brackets around the layer tags. This change simply updates the string replacement to include the square brackets so you would get instead:

```
([a] - [b]) / ([a] + [b])
```

09fc2c3406 Highlight NOT NULL target fields in the Refactor fields algorithm's UI: 
+ By adding a new 'NOT NULL' column in the mapping widget, and
+ By adding an orange color (same as used in attribute form warnings) to the whole row.

New paragraph added to help panel to let users know why some rows are coloured.
