A programming language

## 0.4.5

- The "compile" CLI command has a new option; --pretty which formats the generated code in a human-readable manner. If --optimization-level is 0 (zero), this flag is always enabled thus it only makes sense to pass this when --optimization-level is higher than 0 (zero).
- The "compile" CLI command has a new option; --no-sort. Source files are sorted by filename by default before compiled unless this (--no-sort) option is specified.
- Changed: When passing a non-function argument to Object.prototype.forEach, throw a TypeError instead of failing later
- Changed: "build-weblib" CLI command: Produce move-VERSION*.js files as well as move*.js files. This makes it easier for people to use a specific version of the library knowing it will not be changed. This change is effective on the website movelang.org starting with 0.4.4 (e.g. http://movelang.org/move-0.4.4.js exists but http://movelang.org/move-0.4.3.js does not).
- Fixed: The dprint runtime function is only imported when the source is wrapped as a module or scoped.


## 0.4.4

- The "import" expression now supports relative imports (e.g. `import .foo, ...bar/baz` is equivalent to `foo = require './foo', baz = require '../../bar/baz'`).
- The EHTML preprocessor now supports implicit view constructor `createView`
- The global variable `__move` has been deprecated. Use the global variable `Move` instead.
- Added a new runtime function "dprint" which is similar to "print" but should be used for debugging and is prefixed by the calling module's id (e.g. `dprint message` is equivalent to `print '['+module.id']', message`).
- Changed Object.prototype.forEach to by default iterate over all properties, not just the object's own properties. The extend runtime function has also changed because of this -- by default the extend function now reads all properties (traverses the complete prototype chain) from the source object.
- EHTML separated into two components (preprocessor and runtime library), making it available from the move-rt library.
- The "compile" CLI command has changed:
  - Changed `-b` short option as alias for `--bundle-standalone` to alias for `--bundle`
  - Renamed `-C` short option as alias for `--basedir` to `-d`
  - Added option `--auto`, `-a` which when set keeps the program running and automatically re-compiles when any source file changes.
  - Added option `--silent` to disable outputting of informational messages
  - Changed behavior: When passing `--basedir` but no input files, all move files found in the base directory are used as input. This enables things like `move compile -abd client/src -o public/bundle.js` to automatically compile all move files in a directory when they change and produce a bundle.
- The "create" runtime function no longer supports passing a constructor function. Whatever object is passed -- function type or not -- the resulting object will have the passed object as its prototype.
- The "extend" runtime function no longer supports passing a modifier function. Whatever object is passed -- function type or not -- the resulting object will receive a copy of the passed object's values.
- NPM installation improvements
