#1268 [PATCH] Improve the styling of numbers in Nim

[Jad Altahan]

This is a rather small improvement patch within the SCE_NIM_NUMBER style to conform more with the Nim syntax. It does the following:

• Breaks the style if the digit separator is two underscores instead of one, e.g. 1__1
• Breaks the style if the number ends with an underscore, e.g. 1_

The patch also fixes a harmless, but annoying bug with decimal points in ranges where the fourth decimal point gets styled as SCE_NIM_NUMBER instead of SCE_NIM_OPERATOR when followed by a sequence of three decimal points. See:

Test cases for x.nim are included in the patch.
