### Bridged Tee Attenuator
Fix issues in translatable strings in .md files: - replace "&sdot;" not displayed on Windows (for some reason) by "&middot" - replace the double space at end of lines by the tag <br> A translatable string cannot ends by 2 spaces, because they are not really visible

___a___ is attenuation in dB<br>
___Z<sub>in</sub>___ is desired input impedance in &#x2126;<br>
___Z<sub>out</sub>___ is desired output impedance in &#x2126;<br>
___Z<sub>0</sub> = Z<sub>in</sub> = Z<sub>out</sub>___
convert last formula to markdown. Make them translatable.

___L = 10<sup>a/20</sup>___<br>
Minor editorial changes to PCB calculator, part 2 Don't use substripts in HTML if there is just a number in the subscript: "R1", not "R<sub>1</sub>", except for characteristic impedance. And of course still use "Z<sub>in</sub>", not "Zin". This is also consistent with the images.

___R1 = Z<sub>0</sub> &middot; (L&minus;1)___<br>
___R2 = Z<sub>0</sub> / (L&minus;1)___
