Modernize scripts

[seisman]

Description of proposed changes

1. Update scripts in doc_modern to modern mode.
2. Delete some unused scripts
   Fixes Update scripts to modern mode #96

[PaulWessel]

Hi @seisman. I forgot to say this but given how the entire documentation is built via cmake (and until we make any major changes to how that works), all test, example, and doc scripts must produce just a PS file (not png, etc as these are produced by cmake). For instance, see the test/exmod set of modern mode scripts there.

[seisman]

So, currently all scripts must generate PS only and set paper size to avoid warnings/errors. Looks like this:

gmt begin map ps
gmt set PS_MEDIA letter
...
gmt end

[PaulWessel]

Yes, except we don't need to set the PS_MEDIA letter since that is set globally by cmake when these scripts are run.

[PaulWessel]

Thanks for all your work @seisman. However, unless I am missing something it looks like many of the scripts do not start with gmt begin and therefore will run in classic mode. Was this intentional?

[seisman]

@PaulWessel I'm still working on it. Currently, I only finished scripts related to common options, e.g. GMT_-B_*.sh, GMT_-J.sh, GMT_-R.sh ...

For other scripts, I only did the renaming of some modules, e.g. psbasemap to basemap. That's why all scripts are changed but some don't run in modern mode.

@PaulWessel I have done following changes in this PR:

1. update most scripts to modern mode
2. delete unused scripts GMT_-OK.sh and GMT_-P.sh

Following scripts are not changed, since I'm not sure what to do with these scripts:

• func_F_iso+.sh (why write to stdout)

• func_F_stand+.sh (why write to stdout)

• GMT_App_F_iso+.sh (seems never used)

• GMT_App_F_stand+.sh (seems never used)

• GMT_App_F_stand+_iso+.sh

• GMT_App_F_symbol.sh (seems never used)

• GMT_App_F_dingbats.sh (seems never used)

• GMT_App_F_symbol_dingbats.sh

• GMT_App_P_1.sh (Shall we remove isolation mode? Because it's similar to modern mode)

• GMT_App_P_2.sh (Shall we remove isolation mode? Because it's similar to modern mode)

• GMT_RGBchart.sh (The script runs in isolation mode)

You can review the changes now and also update these PS files.

[PaulWessel]

Some of these scripts (func_F_iso+.sh etc) are called by other scripts. THey are not exposed to any users via documentation - they are jus there to make certain figures in the appendix. We can leave them as is for now.

Thanks, we will add these in and see if there are any side-effects.
