New pencode tags, more gas analyzer info, refactoring and bug fixes

[Nirnael]

• Refactored some comments and a ..() and removed an unused log string for admins, fixed robot inventory bug. Removed some trailing whitespace automatically.

• Gas analyzers now have a switchable operation mode in the UI menu called switch modes with a new mode that shows total mole count and moles per gas in the mixture as well as volume of the mixture. Also added a codex entry to explain how all 3 modes work.

• New pencode tags [pre] [fontblue] [fontred] [fontgreen] for digital use only (nanoword, emails, reports, software txt files, etc.) which cannot be used when writing with a pen on paper. [Pre] has a closing tag and all three fonts are universally closed with [/font]. Fonts just change the font color same as a multicolor pen does, and [pre] is the html <pre> tag that conserves whitespace spaces but apparently not tabs. Printing papers conserve them and can be scanned back into a device with a scanner module giving back the correct pencodes.

rscadd: Adds pencode tags [pre] [fontblue] [fontred] [fontgreen], with closing [/pre] and [/font] universal for the three fonts. They only work digitally with nanoword, emails, report editors and direct txt files. Font color gives color, [pre] gives monospace font and preserves whitespace spaces only and not tabs, e.g. for ascii art.
rscadd: Gas analyzers now show total moles, total volume and moles per gas, check codex for more info.
bugfix: Fixed robot inventory not updating automatically when dropping items which are stored back into it.
bugfix: Saving emails to a txt file on disk now works correctly and can be printed with the new tags.

Not sure moles should be in default mode of analyzer, maybe in detailed one? Same with total moles and volume, that's a lot of info to show in a thing that is usually spammed by non-engineers to see if pressure is changing.

Reworked the scanner and edited the OP for more info
