Battery percentage calculated

[bjarketrux]

A small refactor of the way the battery percentage icon is selected.
Using Math.floor to calculate the "rounded" value.

@igorkulman Inspired by PR #119

Mini test:

Display percentage 0 based on 0
Display percentage 0 based on 1
Display percentage 0 based on 4
Display percentage 5 based on 5
Display percentage 5 based on 6
Display percentage 45 based on 49
Display percentage 50 based on 50
Display percentage 50 based on 51
Display percentage 95 based on 99
Display percentage 100 based on 100

Looks good. Can you please increment the version number in package.json?

Any update when this fix will be released?
I like to use only this tool without the need to active the apple battery icon.

I would love to see 1.1.5 also with this fix. Thank you so much

Apologies for the delay, life has been busy. Merging now and compiling a new version.
