Moved the graphs below the toolbar and made them taller, so that they
are more readable/usable. Converted the statusbar into a box, moved it
below the graphs and rearranged the content to match the graphs.
- move the percentage calculation to init_timeout(), use g_format_size() here too
- carry memory/swap used vs total all around
- make the XtmProcessStatusbar swap and memory properties strings instead of float
Based on a diff from Ján Sucan, thanks!
Note to translators: this changes some strings, mostly removing % in format printing
A leak occured in the timer code, and thus the memory was growing over
time. Cf. src/task-manager.c(model_update_tree_iter), the old_state
variable was not free'd.
Plugged other static leaks at the same time.
Fixed old-style function definitions, dropped unused variables, renamed
signal to xtm_signal (it shadowed a previous global declaration from
signal.h,) dropped the G_UN/LIKELY calls, missing includes and casted
here and there.
The task-manager-*.c files /would/ have to be individually fixed.
Added the TaskManager class to hold system information and tasks.
Currently it provides username and hostname based on POSIX functions.
The Swap is now part of the system information and is being displayed in
the statusbar.
The statusbar is created since a separate widget class and has three
different labels (settable through properties) for CPU, memory and
number of processes. This makes it more convenient to change one or
another value and it gives a nicer look.
