Problems with grammars for numbers

Description:

The grammar for path data uses the following grammar:
[[
floating-point-constant:
fractional-constant exponent?
| digit-sequence exponent
]]
It seems that if no fractional-constant is used (no '.') an exponent component is required.

The same problem is present in the grammar for points in polygons and polylines, because the grammar is duplicated.

Then, the <number> datatype is not aligned with the number token in path (or polygons, polylines). For example, "10." is aligned in a path but not in <number>.

Finally, there should be tests in the test suite with:
- a number with no digit after and before a "."
- a number no digit after exponent
