Refactor build system, simplify templates and escape macros in code

Refactor build system into several modules:
- `settings.py`: to provide common settings (from `buildsettings.py` / `localbuildsettings.py`)
- `build_plugin.py`: to build single plugin
  formats userscript metablock, preprocesses sources - makes templates substitutions,
  inlines dependencies js/css/img - and wraps into wrapper (from `pluginwrapper.py`)
  - `pluginwrapper_noinject.py` - alternative wrapper, useful for debugging scripts.
     Sample usage in `buildsettings.py`, for build name 'tmdev'.
- `build_mobile.py`: to build android apk (embedding scripts from given directory)
- `build.py`: to build all: main IITC script, all plugins, and (optionally) Android apk.
  - `--watch` mode (auto-rebuild on sources changes)

Each module can be used independently as cli utility.

Escape macros in code in order to keep js-validity, fix IITC-CE#50.
Simplify userscripts source template, completely get rid of these ugly substitutions:
- `@@MetaInfo@@`
- `@@PLUGINSTART@@`
- `@@PLUGINEND@@`
- `.@@DATETIMEVERSION@@`
- `[@@Buildname@@-@@BUILDDATE@@]`

Close IITC-CE#150: use template from settings instead of url harcoding.

Close IITC-CE#99: remove timestamp component from `version` of Release scripts.

Rename plugin sources:  `*.user.js` -> `*.js`

Additional dev utilities:
- `web_meta_gen.py` to generate meta.json for IITC-Button.
  Can be used as standalone cli, or as part of build process.
- `web_server_local.py` to start local webserver for specified build name.
