tools: Minor fixes to the tool documentation for "ceylon bash-completion"
tools: Add support for docbook as an output format for 'ceylon doc-tool'.
This means it's now relatively simple to produce groff format (i.e. man pages)
by using a tool such as db2x_docbook2man, but I'll leave it to those who
create the .rpms and the .debs to actually do that.
tools: Add a common ModuleSpec class which can be reused by tools which take module specs as arguments
tools: Change CeylonImportJarTool to use the new ModuleSpec class instead of doing its own thing. Note: I'm also disallowing to import a jar as the default module, because I can't see how that would ever be useful
tools: Change CeylonDocTool to use the new ModuleSpec class instead of doing its own thing.
tools: Issue #1035: A bare-bones implementation of 'ceylon src' (aka CeylonSrcTool),
lacking tests.
tools: Some work tidying up tool i18n
tools: Minimal l10n of some tools to prove we can actually generate ceylon help output in another language. Apologies to Stef, Emmanuel, David and anyone else who actually speaks French: My schoolboy French is sufficiently bad that I had to use google translate for these, so I suspect they're not great.
tools: Issue #1035: A bare-bones implementation of 'ceylon info', lacking tests and missing output for module license and description
