Added some date and time formatting options to scrolling text effect.

[5chubrakete]

Added/updated the following tags to use with the scrolling text effect.

#hh Hours
#mm Minutes
#ss Seconds

#DD Day
#MM Month
#MMM Month as Text
#YYYY Year
#YY Two digit Year

Changed #hhmm to lower case to not get confused with month.

This enables more flexible display of time and date on a bigger matrix. Also beeing able to display seconds in smaller font or lower brightness.

Why not just uppercase text (if it starts with #) and add "#YY" and "#YYYY"?

[softhack007]

Why did you remove #HHMM and #HH ?
Some user might have them in their preset. We should stay backwards-compatible.

[softhack007]

Same problem here - changing the meaning of #MM from "minutes" to "month" is not backwards-compatible either.

[blazoncek]

Agreed. This is an unacceptable change.

[blazoncek]

I would suggest you uppercase text and then do formatting.
I.e.

if (text[0] == '#') for (auto &c : text) c = std::toupper(c);

[blazoncek]

Agreed. This is an unacceptable change.

[blazoncek]

Perhaps a better way is year(localTime)%100 instead of subtracting 2000.

[5chubrakete]

Agreed on %100 way and keeping it backwards-compatible. I dont get the upper case part.
So keep #HH, #MM and add #MON, #MONTH, #SS, #YY, #YEAR ?

Here's a nonbreaking change:

    if (text[0] == '#') for (auto &c : text) c = std::toupper(c);
    if      (!strncmp_P(text,PSTR("#DATE"),5)) sprintf_P(text, zero?PSTR("%02d.%02d.%04d"):PSTR("%d.%d.%d"),   day(localTime),   month(localTime),  year(localTime));
    else if (!strncmp_P(text,PSTR("#DDMM"),5)) sprintf_P(text, zero?PSTR("%02d.%02d")     :PSTR("%d.%d"),      day(localTime),   month(localTime));
    else if (!strncmp_P(text,PSTR("#MMDD"),5)) sprintf_P(text, zero?PSTR("%02d/%02d")     :PSTR("%d/%d"),      month(localTime), day(localTime));
    else if (!strncmp_P(text,PSTR("#TIME"),5)) sprintf_P(text, zero?PSTR("%02d:%02d%s")   :PSTR("%2d:%02d%s"), AmPmHour,         minute(localTime), sec);
    else if (!strncmp_P(text,PSTR("#HHMM"),5)) sprintf_P(text, zero?PSTR("%02d:%02d")     :PSTR("%d:%02d"),    AmPmHour,         minute(localTime));
    else if (!strncmp_P(text,PSTR("#HH"),3))   sprintf  (text, zero?    ("%02d")          :    ("%d"),         AmPmHour);
    else if (!strncmp_P(text,PSTR("#MM"),3))   sprintf  (text, zero?    ("%02d")          :    ("%d"),         minute(localTime));
    else if (!strncmp_P(text,PSTR("#SS"),3))   sprintf  (text,          ("%02d")                     ,         second(localTime));
    else if (!strncmp_P(text,PSTR("#DD"),3))   sprintf  (text, zero?    ("%02d")          :    ("%d"),         day(localTime));
    else if (!strncmp_P(text,PSTR("#DAY"),4))  sprintf  (text,          ("%s")                       ,         dayShortStr(day(localTime)));
    else if (!strncmp_P(text,PSTR("#DDDD"),5)) sprintf  (text,          ("%s")                       ,         dayStr(day(localTime)));
    else if (!strncmp_P(text,PSTR("#MO"),3))   sprintf  (text, zero?    ("%02d")          :    ("%d"),         month(localTime));
    else if (!strncmp_P(text,PSTR("#MON"),4))  sprintf  (text,          ("%s")                       ,         monthShortStr(month(localTime)));
    else if (!strncmp_P(text,PSTR("#MMMM"),5)) sprintf  (text,          ("%s")                       ,         monthStr(month(localTime)));
    else if (!strncmp_P(text,PSTR("#YY"),3))   sprintf  (text,          ("%02d")                     ,         year(localTime)%100);
    else if (!strncmp_P(text,PSTR("#YYYY"),5)) sprintf_P(text, zero?PSTR("%04d")          :    ("%d"),         year(localTime));
