Avoid the presence of tab characters in scripts

Hi,

The scripts provided with zAppbuild use the tab character to manage indentations.

On the one hand the equivalent in space characters depends on an option of the editor used, and the rendering will not be the same from one site to another, but on the other hand it complicates the work when must edit a script directly under ISPF/PDF:

• emission of alert message on the presence of non-displayable characters
• impossible to enter a display character instead of a tabulation character in the editor, (it is necessary to switch to hex display, replace the tabulation character by a displayable character, then deactivate the hex mode).

Even if the direct modification under ISPF/PDF of the script files is not to be recommended, zAppbuild remains a z/OS application and must be able to be managed in native z/OS mode.

Tab characters should therefore not be used in zAppbuild's groovy scripts.

PS : avoid also blank or tab at end of line 😁

Another reason for not using tabs: for our developments we plan to use an extension Groovy Lint, Format and Fix
