QoL improvements for code, updated battery display code, and more

[ironswordX-dev]

• Improve battery display message (QOL) #35 by @Ant-Throw-Pology was the baseline for updated battery display code, I turned most of the needed code to generate the time left into its own function that automatically gives outputs depending on inputs (e.g. if the function is given 0 as the hours left and 15 as the minutes left, it will give Around 15 minutes left until (direction) rather than Around 0 hours 15 minutes until (direction))
• Improved function importing for the new tab javascript files using the default tag in export statements
• File that contains all the urls needed (still working on)
• Added a link w/ a small instruction dialogue to add/connect/etc. wifi networks using chrome://network/#select
• And a few other miscellaneous things

most of this seems okay. but a few nitpicks:

• wifiselect.js is not a valid file name, it should be wifi-select.js
• the URL thing should not be called "URL" with all uppercase, that conflicts with the actual api built in
• I'd prefer if you named that object UrlConstants, export defaulted it, then did "import UrlConstants from 'url-constants.js'", then referenced those as UrlConstants.HISTORY_URL
• Just to recap, "wifiLink" html/css class should be "wifi-link". "wifilink" js variable should be "wifiLink"
• Also what is "import { openTab } from "./../wifiselect.js";"??? i dont see this file anywhere

If you do all these i'll merge
