Enhancements and Fixes Found While Testing Code Base

[engineerjoe440]

I've found a number of little things that were causing some trouble while I was testing this project against a number of 61131 repositories, I've made a bunch of smaller, incremental branches for each stage of work, so if you'd prefer going through one at a time, let me know!

Changes:

• Add Support of VAR_EXTERNAL in Functions.
• Allow DateTimes to exclude seconds/fractional-seconds (both appear to be legal options for 61131).
• Support Arrays of FunctionBlocks that use an FB_init inline. example
• Allow "Stray" semicolons that would otherwise have no effect.
• Allow Namespaced (dotted) access to structures in declaration when setting a default. example
• Separate Global Variable Attributes to allow inclusion of "INTERNAL".
• Allow function call with empty arguments. example

Closing Thoughts:

Please do let me know if you'd rather take a piecemeal approach to this, I've still got all of the branches, and we can work each one in separately. If there's anything that I've missed (clearly I've done that a time or two before), please let me know! I'm happy to get this all cleaned up.

I'm finding this project very useful, thank you!

I haven't forgotten about this - it's still on my TODO list. To your question, I'm OK with bunching these changes into one PR.

Hope to get back to you soon, and thanks! 👍

Don't worry about it! Heh! I wouldn't have been able to do anything this week if you asked for changes, anyway! Thank you!
