Compute checksum internally without calling md5sum
Search PIDs manually instead of calling pidof
Optimize performance - avoid QRegExp

Use string searching wherever possible instead of constructing temporary
regular expressions, and if a regexp is required, use QRegularExpression
instead.

These changes reduce loading time from ~3.5 seconds to ~2.3 seconds.

Add qtdeclarative5-dev to apt-get. fixes #111
Merge pull request #116 from wRAR/DF2014

Desktop file fixes.
fixes #69

- adds a log message and placeholder health information if it's missing
from the game_data.ini (most likely due to manual updating)
fixes tooltip bug, script nicknames, caged civs

- updated how the unit's are refreshed on commits/clears so it's more
optimized and doesn't do an entire read. this also resolves the issue
where preferences and skills were doubled/tripled because each time a
pending commit was cleared, a full read of everything was done
- updated the buffer size when writing/reading the labors (it was too
large)
- added the nickname() function for scripts
- changed the validation for caged creatures to allow for caged civ
members to still show up (untested)
