fxsdk: command-line interface for fxSDK 2.3

* Add the CMake build system
* Use CMake as the default for new projects
* Change [fxsdk new] but continue supporting the previous signature
* Automatically configure in [fxsdk build-fx] and [fxsdk build-cg]
* Improve help screen

 This program is a command-line helper for the fxSDK, a set of tools used in
 conjunction with gint to develop add-ins for CASIO fx-9860G and fx-CG 50.
 
-Project creation:
-  fxsdk new <folder>
+${R}fxsdk new${n} ${g}<FOLDER>${n} [${R}--makefile${n}|${R}--cmake${n}] \
+[${g}<NAME>${n}]
+  Create a new project in the specified folder. The default build system is
+  CMake. Project name can be specified now or in the project files later.
 
-  Creates a new project in the specified folder. Project info is input
-  interactively. Creates <folder name> and populates it with default project
-  data.
-
-Compilation:
-  fxsdk build [-s]
-  fxsdk build-fx [-s]
-  fxsdk build-cg [-s]
-
-  Compiles the current project for fx-9860G (.g1a target) or fx-CG 50 (.g3a
+${R}fxsdk build${n} [${g}-s${n}]
+${R}fxsdk build-fx${n} [${g}-s${n}]
+${R}fxsdk build-cg${n} [${g}-s${n}]
+  Build the current project for fx-9860G (.g1a target) or fx-CG 50 (.g3a
   target). With 'fxsdk build', compiles every existing build folder, and ask
   interactively if none is found.
 
   With '-s', also sends the resulting program to the calculator.
 
-Installation:
-  fxsdk send
-  fxsdk send-fx
-  fxsdk send-cg
-
+${R}fxsdk send${n}
+${R}fxsdk send-fx${n}
+${R}fxsdk send-cg${n}
   Sends the target file to the calculator. Uses p7 (which must be installed
   externally) for fx-9860G. Currently not implemented for fx-CG 50, as it
   requires detecting and mounting the calculator (same for the Graph 35+E II).
 
-Project update:
-  fxsdk update
-
+${R}fxsdk update${n}
   Copies the latest version of the Makefile to your project. *This will
   discard any changes made to your Makefile.* If you have edited your
   Makefile, make a backup and merge the changes after updating.
