Running from a subdirectory makes the entire script a bit cumbersome
to wrap around when it comes to relative paths. They should now all work
properly though.
Paths that are relative to the Project Root now work as expected (eg.
package.json path) and other paths like the data and config path are
based on the current execution directory.
The issue with ambigous characters is that they are hard to write
when only seeing them, as one could confuse 0 for O with certain
typefaces for example.
Ambiguity is lessened by removing `Oo0Iil1` from the possible charset.
In order to keep a big enough pool of IDs the ID length changed from 6
to 8 characters instead, which seems like an OK tradeoff.
This is currently untested, but the backend allows creating a new poll,
getting results of an existing poll, voting and retrieving info of a
poll for display purposes.
Recaptcha is not yet implemented at this stage.
