Summary:
Changed UseTab to be a enum with three options: Never, Always,
ForIndentation (true/false are still supported when reading .clang-format).
IndentLevel should currently be propagated correctly for all tokens, except for
block comments. Please take a look at the general idea before I start dealing
with block comments.

After:

Re-add logic to prevent breaking after an empty set of parentheses.
Basically it seems that calling a function without parameters is more
like navigating along the same object than it is a separate step of a
builder-type call.

We might need to extends this in future to allow "short" parameters that
e.g. are an index accessing a specific element.
