Add new text objects to retrieve the currently used keyboard layout and mouse speed in percentage and generate random password of chosen length and get the cpu clock speed from assembly (#550)

* Add new text object to capitalize the first character of each word

* Fix for issue https://github.com/brndnmtthws/conky/issues/46

* Fix for issue https://github.com/brndnmtthws/conky/issues/35

* Fix for issue https://github.com/brndnmtthws/conky/issues/35

* Fix for https://github.com/brndnmtthws/conky/issues/206

* Fix for https://github.com/brndnmtthws/conky/issues/474

* Add new "temp2" variable to print the temperature in floating number

* Make the "temp2" variable static and add some explanation above it

* openbsd.cc: Add one more formal parameter to "temp_print()"

* extras/convert.lua: change url to wiki page (#554)
