Report version date as Unix epoch instead of preformatted string

[digitalcircuit]

In brief

• Report version date as Unix epoch
  • ClientDate field, seconds as a string for backwards compatibility
  • Quassel desktop v0.13 and higher will format the date/time locally

Details

After looking at issue #22, I noticed that iQuassel currently pre-formats the version date instead of reporting the date/time in seconds since the Unix epoch:

QuasselCoreConnection.m

NSString *dateStr = [NSString stringWithFormat:@"%@ %@", [NSString stringWithUTF8String:__DATE__], [NSString stringWithUTF8String:__TIME__]];
[initial setValue:[[QVariant alloc] initWithString:dateStr] forKey:@"ClientDate"];

iQuassel should instead send the version date as the seconds since the Unix epoch, wrapped as a string for backwards compatibility. For example, Quassel desktop does this:

src/common/quassel.cpp

// Set to Unix epoch, wrapped as a string for backwards-compatibility
buildInfo.commitDate = QString::number(GIT_COMMIT_DATE);

Quasseldroid also transmits the ClientDate as a string of seconds since the Unix epoch.

Quassel desktop v0.13 and newer will automatically format this using the date/time locale of the current system, as per the screenshots in the upstream PR.
