The type "enum" replaces type "integer" when used with string values.
For compatibility, any option created with type "integer" and string values is
automatically created to "enum" on creation, with no error.
Changes:
- build of doc now requires weechat-headless, translations and all plugins
- convert docgen.py to C
- remove `autogen_*` files from repository
- add command line parameter `--doc-gen` in `weechat-headless` to build
autogen files
- build .mo files with directories like the installed ones
(eg: "<lang>/LC_MESSAGES/weechat.mo")
- remove javascript chapter from user's guide
