don't shadow local variable in "Time::fromString()"

cutting away the ":millisecond" part of the string is not needed, as
"strptime()" will simply not consume characters after a successfull
match. to make matters worse, the lifetime of the newly created,
shadowing variable was only limited to be inside the if-clause and had
no effect to the rest of the function anyways...

fixes compiler warning.

fix shadow-warnings in constructor of "Waypoint"

while changing the lines anyhow: do some re-formatting, add some comments

NOTE: the default-constructor initialized with identity/zero before --
this might not be the behavior that was discussed on the mailinglist?

remove semicolons after empty constructor-implementation.

fix shadow-warnings in various functions of "Frame"

here I'm not sure if there are actually shadow bugs hiding in the
dark... anyhow, fix all the warnings.

change some variables to more informative names. hopefully I got them
all correct ;-)
