Previously using `dscanner --ctags -R <dir>` would output tags without
any filenames, making it pretty useless for navigating in a project.
This was due to all the syntax objects being merged into a single generic
Module, then outputting that module without a filename specified.
This fix does the following:
* Moves the CTag header output from the Module class to the proper spot in
main.d
* Renames `Module.writeCtagsTo` to `getCtags` and now returns string[]
with the prepared tag lines.
* The CTag printing functionality in main.d now gathers all tag lines
from each module, sorts, then outputs.
Note that a more optimal implementation would be fairly straightforward.
Instead of simply returning a string[], `Module.toCtags` could take a
sorted container and insert in sorted order. main.d could pass this
container to each module in turn, then output the results.
Alphabetized constants
Cleaned up constant names
Fixed defects with decimal parsing
Eliminated iteration style parameter to lexWhitespace, as it didn't really speed things up.
Added support for imaginary literals
